150 - x - 2x = 120 + 2x
Svetach [21]

Answer:

x = 6

Step-by-step explanation:

Step 1: Write equation

150 - x - 2x = 120 + 2x

Step 2: Solve for <em>x</em>

  1. Combine like terms: 150 - 3x = 120 + 2x
  2. Add 3x to both sides: 150 = 120 + 5x
  3. Subtract 120 on both sides: 30 = 5x
  4. Divide both sides by 5: 6 = x
  5. Rewrite: x = 6

Step 3: Check

<em>Plug in x to verify it's a solution.</em>

150 - 6 - 2(6) = 120 + 2(6)

144 - 12 = 120 + 12

132 = 132
