4(2x - 5) = 3x + 10               Given

8x - 20 = 3x + 10                  Distribute the 4

8x -20 + 20 = 3x + 10 + 20    Add 20 to each side

8x = 3x + 30                         Simplify

8x - 3x = 3x + 30 - 3x            Subtract 3x from each side

5x = 30                                Simplify

5x/5 = 30/5                          Divide each side by 5

x = 6                                    Simplify
