Answer:
option B)
x = 2
Explanation:
Given in the question the equation:
10x - 3(x- 6) = x + 30
Simplify the left side
10x - 3(x - 6) = x + 30
10x - 3x + 18 = x + 30
rearrange the terms and containing x to the left side of the equation and add accordingly
x(10 - 3 - 1) = (30 - 18)
x(10 - 4) = (12)
x(6) = 12
6x = 12
Divide each term by 6 and simplify
x = 12/6
x = 2
