Exercise 67 Page 452

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

2x-y=13

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+3=2(x-5)
Distr

Distribute 2

y+3=2x-10
SubEqn

LHS-y=RHS-y

3=2x-10-y
AddEqn

LHS+10=RHS+10

13=2x-y
RearrangeEqn

Rearrange equation

2x-y=13

Below we compare this result with the general standard form equation. Ax+ By&= C 2x - 1y&= 13
