Exercise 32 Page 326

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

4x+(-1)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 and A and B cannot both be zero. We will use the Properties of Equality to rewrite the given equation in this form.

y+3=4(x-1)

Distr

Distribute 4

y+3=4x-4

AddEqn

LHS+4=RHS+4

y+7=4x

SubEqn

LHS-y=RHS-y

7=4x-y
