You will need to apply the Properties of Equality, solving until the equation is in standard form.
3x-4y=- 20
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.
LHS * 4=RHS* 4
LHS-20=RHS-20
LHS-4y=RHS-4y
Rearrange equation
Now we can see that our equation follows the standard form. Ax+ By&= C 3 x - 4y &= - 20
