Exercise 71 Page 452

You will need to apply the Properties of Equality, solving until the equation is in standard form.

9x-36y=- 108

Practice makes perfect

Equations in standard form are written in a specific format. Ax+ By= CIn this form, A, B, and C are integers. Besides, A and B cannot both be zero. We will use the Properties of Equality to rewrite the given equation in this form.

9y=9x/4+27
MultEqn

LHS * 4=RHS* 4

36y=36x/4+108
ReduceFrac

a/b=.a /4./.b /4.

36y=9x+108
SubEqn

LHS-36y=RHS-36y

0=9x+108-36y
SubEqn

LHS-108=RHS-108

- 108=9x-36y
RearrangeEqn

Rearrange equation

9x-36y=- 108

Below we compare this result with the general standard form equation. Ax+ By&= C 9x - 36y&= -108
