Question

What is the value of x in the equation 4(2x + 14) = 0? a 9 b 7 c −7 d −9

Answer 1

C, -7

Explanation:

Use distributive property to get: 8x +56 = 0

Isolate x to get: 8x = -56

Then divide each side by 8: x= -7

The answer is C

Answer 2

x = -7

Explanation:

4(2x + 14) = 0

Divide each side by 4

2x+14 = 0

Subtract 14 from each side

2x+14-14 = 0-14

2x= -14

Divide each side by 2

2x/2 = -14/2

x = -7
