Question

I CAN DETERMINE IF A VALUE IS TRUE GIVEN AN EQUATION.

9. If x = -3, then which of the following equations are true? Put a checkmark on all that apply.
Χ
3-9= 15
-2x+18=24
6x +9=-13
4x-9=-21

Answer 1

-2(-3)+18=24

6+18 = 24

24 = 24

correct

6(-3) +9=-13

-18+9 = -13

-9 ≠ - 13

Wrong

4(-3)-9=-21

-12 -9 =-21

-21 = -21

Correct
