Question

Eight times a number added to -8, subracted from twice the sum of three times the number and 8

Answer 1

9x + (-8) - 2(3x + 8)

Answer 2

Eight times a number (x) added to -8
8x + (-8 )
Subtracted from twice the sum of 3 times a number and 8
2(3x + 8) - 8x + (- 8)

Answer 3

I take that back.
You should have: 2(3x + 8) - (8x - 8) You need to subtract the entire quantity of (8x - 8)

Distribute and solve for x.

Answer 4

6x + 16 -8x + 8 = 0
24 = 2x
12 = x
