Question

100 + 2x = 140 + 6x

Answer 1

{-10=x } is the answer

Answer 2

-10 =x

Explanation:

100 + 2x = 140 + 6x

Solve for x

Subtract 2x from each side

100 + 2x-2x = 140 + 6x-2x

100 = 140 +4x

Subtract 140 from each side

100-140 = 140+4x-140

-40 = 4x

Divide each side by 4

-40/4 = 4x/4

-10 =x
