Liza needs help to solve this linear equation. 4(x – 5) + 2x = 9x – 2(4 + 2x) She has completed two steps, but now she’s stuck. Examine her work. 1. 4x - 20 + 2x = 9x - 8 - 4x 2. 6x - 20 = 5x - 8 What could be the next step? Select all that apply. Add 8 to both sides.
Add 5x to both sides.
Subtract 6x from both sides.
Subtract 20 from both sides.
Divide both sides by –8.
Divide both sides by –20.
