Check the boxes that describe the correct process to solve this equation.

4x + 6 = 18

• First step is to subtract 6 from both sides

  leaving 4x=12

• First step is to divide both sides by 4

  leaving x + 6 = 4.5

• Second step is to divide both sides by 4

  leaving x = 3

• Second step is to subtract 6 from both sides

  leaving x = - 2.5
