Question 916644
To solve this problem, we must find where 3x - 12 = 26 + x

Move all terms containing x to the left, all other terms to the right.

Add '-1x' to each side of the equation.
-12 + 3x + -1x = 26 + x + -1x

Combine like terms: 3x + -1x = 2x
-12 + 2x = 26 + x + -1x

Combine like terms: x + -1x = 0
-12 + 2x = 26 + 0
-12 + 2x = 26

Add '12' to each side of the equation.
-12 + 12 + 2x = 26 + 12

Combine like terms: -12 + 12 = 0
0 + 2x = 26 + 12
2x = 26 + 12

Combine like terms: 26 + 12 = 38
2x = 38

Divide each side by '2'.
x = 19

Simplifying
x = 19

Check: 3*19 = 57 - 12 = 45
26 + 19 = 45
