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!!!! : )

x is 18

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