Answer:

The answers to your questions are:

a) x = 14

b) x = 25

Step-by-step explanation:

a)   (7x -1) + (6x -1) = 180

     7x -1 + 6x -1 = 180

      7x + 6x = 180 + 1 +1

      13x = 182

       x = 182/13

       x = 14

b)   5x +4 = 8x - 71

     8x - 71 = 5x + 4

      8x - 5x = 71 + 4

      3 x = 75

      x = 75 / 3

      x = 25
