since it's absolute value, you'd make it 3+2x=7. from there you subtract 3 from both sides and get 2x=4. divide both sides by 2 and get that x=2.

Answer:

x = -2 x=5

Explanation:

|3 - 2x| = 7

Absolute values are split into two equations, one positive and one negative

3 - 2x = 7 3 - 2x = -7

Subtract 3 from each side

3-3 - 2x = 7-3 3-3 - 2x = -7-3

- 2x = 4 - 2x = -10

Divide each side by -2

-2x/-2 = 4/-2 -2x/-2 = -10/-2

x = -2 x=5
