Exercise 5 Page 357

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

3x-4y=- 20

Practice makes perfect

Equations in standard form are written in a specific format. Ax+ By= C,In 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=3/4x+5

LHS * 4=RHS* 4

4y=3x+20

LHS-20=RHS-20

4y-20=3x

LHS-4y=RHS-4y

- 20=3x-4y

Rearrange equation

3x-4y=- 20

Now we can see that our equation follows the standard form. Ax+ By&= C 3 x - 4y &= - 20
