You can  put this solution on YOUR website! 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
