Round to the near at tenth

| 3x + 1 | = 22

x = 7 x = - 7 2/3

Step-by-step explanation:

| 3x + 1 | = 22

Absolute value equations have 2 solutions, one positive and one negative

3x+1 = 22 3x+1 = - 22

Subtract 1 from each side

3x+1-1 = 22-1 3x+1-1 = - 22-1

3x = 21 3x = - 23

Divide each side by 3

3x/3 = 21/3 3x/3 = - 23/3

x = 7 x = - 7 2/3
