Answer 2

2x + 5 = 27               2x = 27 - 5        2x = 22           x= 11

4x - 8 = 2x + 6          4x - 2x = 6 + 8      2x = 14       x = 7

7x + 1 = 6x + 6         7x - 6x = 6 - 1     1x = 5          x = 5

5x - 3 = 2x - 9           5x - 2x = -9 + 3      3x = -6      x = -2

4x - 7 + x = 1           4x + 1x = 1 + 7      5x = 8        x = 8/5

3 - 2x = 4x             3 = 4x + 2x         3 = 6x        x= 3/6     x = 1/2
