Exercise 66 Page 452

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

4x-y=-7

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.

y=4x+7

SubEqn

LHS-y=RHS-y

0=4x+7-y

SubEqn

LHS-7=RHS-7

- 7=4x-y

RearrangeEqn

Rearrange equation

4x-y=- 7

Below we compare this result with the general standard form equation. Ax+ By&= C 4x - 1y&= - 7
