Exercise 31 Page 326

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

2x+(-1)y=-5

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=2x+5

SubEqn

LHS-5=RHS-5

y-5=2x

SubEqn

LHS-y=RHS-y

-5=2x-y
