1)|X-5| = 12

- 12 = X-5 = 12

-7 = X = 17

2) |X+5| = 0

-5 = X = -5

3) |X - 8| = -1

1 = X - 8 = -1

9 = X = 7

4) 7.8 - x = 9.3

-x = 9.3 - 7.8

-x = 1,5

x = - 1.5

5) y - (-17,85) = 12

y + 17,85 = 12

y = 12 - 17,85

y = -5,85

6) 5 5/12 + z = -3 1/3

65/12 + z = -8/3

z = -8/3 - 65/12

z = (- 32 - 65) / 12

z = - 97 / 12

z = - 8,083
