2. System of equations

• Setting equations same to each different

To prevail in the SAT math no calculator phase, you need to recognise when to set equations identical to each other to find a solution. As an instance, you may want to set two variables, along with a rate consistent with pound of beef and hen, equal to each other to discover an answer.

🚀 Example

You may additionally encounter a hassle like this: “Beef prices $three in line with pound and bird fees $2 consistent with pound. If you spent the equal amount in shopping for 10 kilos of red meat and 𝑐

c kilos of fowl, how an awful lot of chook did you buy?” In this case, you’ll set the whole charges of pork and fowl identical to each other to discover the load of hen. The equation could be:

$three/pound×10 pounds=$2/pound×𝑐 kilos

 

$three/pound×10 kilos=$2/pound×c pounds.

 

To solve for the weight of chickcen:

$30=$2𝑐.

$30=$2c.

 

Weight of hen(𝑐)=15 kilos

Weight of chicken(c)=15 kilos.

• Simplifying equations

Simplifying equations is an essential strategy for making them more plausible and simpler to solve on the SAT math no calculator segment. This includes using techniques like pass-multiplication and combining like phrases to simplify equations and isolate variables. In order to correctly simplify equations, you need to have a sturdy basis in algebraic operations.

🚀 Example

Given an equation like 2.35+zero.25𝑥=1.75+0.40𝑥

2.35+0.25x=1.Seventy five+0.Fortyx, you can simplify it by means of subtracting 0.25𝑥

0.25x from both facets to get:

2.35=1.75+0.15𝑥.

2.35=1.Seventy five+0.15x.

 

 

Then, you could subtract 1.75

1.75 from each aspects to isolate the variable:

0.60=0.15𝑥.

zero.60=0.15x.

 

 

Finally, you may divide both facets via 0.15

zero.15 to resolve for 𝑥

x:

𝑥=four.

x=four.

• Using substitution

To simplify SAT math problems that contain multiple equations, you could use substitution. Start through keeping apart one of the variables in one of the equations, and then alternative its value into the other equation.

🚀 Example

Start with the 2 given equations: 𝑦−4=3𝑥

y−4=threex and 2𝑥+𝑦=10

2x+y=10.

Isolate 𝑦

y inside the first equation by means of including four

4 to both sides: 𝑦=3𝑥+four

y=3x+four.

 

Substitute the resulting expression 𝑦=3𝑥+4

y=threex+four into the second one equation in area of 𝑦

y, supplying you with: 2𝑥+(3𝑥+4)=10

2x+(threex+four)=10.

 

Simplify the equation by means of combining like terms: 5𝑥+four=10

5x+4=10, that’s equivalent to 5𝑥=6

fivex=6.

 

Solving for 𝑥

x: 𝑥=1.2

x=1.2.

This method of substitution eliminates one variable, making it easier to solve for the final variable.

1

​:

Start on the y-intercept (0,zero)

(zero,0).

 

Move up one unit and to the proper seven devices to locate another point on the road.

 

Plot the 2 points (zero,0)

(zero,0) and (7,1)

(7,1).

 

Draw an immediate line through the two factors.

 

This line has a slope of 17

7

 

1

​ and passes via the factors (zero,zero)

(0,0) and (7,1)

(7,1).

• Using trigonometric identities

You must be capable of understanding that the sine of a perspective is the same as the cosine of its complement and use this dating to clear up issues.

One example of the use of the trigonometric identification sin⁡𝑥=cos⁡(ninety∘−𝑥)

sinx=cos(ninety∘

−x) is: Given that sin⁡30∘=0.Five

sin30∘

=0.5, discover cos⁡60∘

cos60∘

.

Recognize that cos⁡60∘

cos60∘

 is identical to sin⁡30∘=0.5

sin30∘

=0.Five.

• Solving for angles and aspects

To discover the lengths of sides in a triangle, you can rely on a handy tool known as SOHCAHTOA. It gives a simple way to recollect how to utilize sine, cosine, and tangent in trigonometry.

🚀 Example

Let’s say you’ve got a proper triangle, and you are given that sin⁡𝑥=45

sinx=five

 

four

​. With this statistics in hand, you can decide the lengths of the edges.

 

Remember that SOHCAHTOA states that sine equals the opposite facet divided by means of the hypotenuse. So, by means of labeling one side as ‘𝑙

l‘ and the hypotenuse as ‘ℎ

h,’ you may installation the following equation:

45=sin⁡𝑥=𝑙ℎ.

5

 

4

​=sinx=h

 

l

​.

 

 

By fixing for ‘ℎ

h,’ you’ll acquire:

ℎ=5𝑙4.

h=four

 

5l

​.

This approach empowers you to find the facet lengths on your triangle using trigonometry, making it a precious tool for tackling comparable issues.
