Question

8(2x – 14) + 13 = 4x – 27


Part B: What value of x makes the equation true? (4 points)

i got part a but i dont understand part b.
the answer is 6 if that helps.

Answer 1

8 (2x - 14) + 13 = 4x -27

distribute 8 through the parentheses

16x - 112 + 13 = 4x - 27

combine like terms

16x - 99 = 4x -27

subtract 4x from each side

12x - 99 = -27

add 99 to each side

12x = 72

divide each side by 12

x = 6
