Question

Round to the near at tenth
| 3x + 1 | =22

Answer 1

x =7 x = -7 2/3

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
