Distribute to get:
2(x - 3) + 21 = -3
2x - 6 + 21 = -3
what about the rest
Combine like terms to get:
2x - 6 + 21 = -3
2x + 15 = -3
Use the (choose a property) Response area to get (resulting equation) Response area
Use the addition property of equality to simplify the equation:
2x + 15 = -3
Use the (choose a property) Response area to get (resulting answer) Response area
Use the subtraction property of equality to solve for x:
2x = -3 - 15
2x = -18
Divide both sides by 2:
x = -18/2
x = -9
