X is 18
You need to algebraically move things around by adding/dividing on both sides (work shown in the picture).

Solve Equation:
3 ( 110 - 7x ) = x - 66
Simplify both sides:
3 ( 110 - 7x ) = x - 66
( 3 ) ( 110 ) + ( 3 ) ( - 7x ) = x + - 66
Distribute:
330 + -21x = x + - 66
- 21x + 330 = x - 66
Step 2: Subtract x both sides:
- 21x + 330 - x = x - 66 - x
- 22x + 330 = -66
Step3: Subtract 330 both sides:
- 22x + 330 - 330 = - 66 - 330
- 22x = - 396
Step 4: divide both sides by - 22:
- 22x / - 22 = - 396 / - 22
x = 18
Answer: 3 ( 110 - 7x ) = x - 66 =====> x = 18
Hope that helps!!!! : )
