Answer:

x = 133                                         x = -7

Step-by-step explanation:

| x/7 - 9| = 10

There are two solutions, one positive and one negative

x/7 - 9 = 10             x/7 - 9 = -10

Add to to each side

x/7 - 9+9 = 10+9             x/7 - 9+9 = -10+9

x/7 = 19                              x/7 = -1

Multiply each side by 7

x/7 *7 = 19 *7                             x/7*7 = -1*7

x = 133                                         x = -7
