Solve the equation 3(2x + 2) = 3x − 15. x = −7 x equals negative seventeen thirds x = 3 x = 7

x = -7

Step-by-step explanation:

3(2x + 2) = 3x − 15

Divide each side by 3

3/3(2x + 2) = 3x/3 − 15/3

2x+2 = x-5

Subtract x from each side

2x+2-x = x-5-x

x+2 = -5

Subtract 2 from each side

x+2-2 = -5-2

x = -7
