Step-by-step explanation:

Step 1: Define

w = 3(2a + b) - 4

Step 2: Solve for a

  1. Add 4 to both sides:                     w + 4 = 3(2a + b)
  2. Divide 3 on both sides:                (w + 4)/3 = 2a + b
  3. Subtract b on both sides:            (w + 4)/3 - b = 2a
  4. Divide 2 on both sides:                (w - 3b + 4)/6 = a
  5. Rewrite:                                         a = (w - 3b + 4)/6
