Step-by-step explanation:

Step 1: Define

6x + 4 = 7

Step 2: Solve for x

  1. Subtract 4 on both sides:                    6x = 3
  2. Divide 6 on both sides:                        x = 3/6
  3. Simplify fraction:                                   x = 1/2

Step 3: Evaluate

  1. Define equation:                    6x - 4
  2. Substitute in x:                       6(1/2) - 4
  3. Multiply:                                  3 - 4
  4. Subtract:                                 -1
