Question

Solve for x.

4 | x - 7 | + 2 | x - 7 | = 12

Answer 1

Answer: x = 9, 5

Explanation:

4 | x - 7 | + 2 | x - 7 | = 12

6 | x - 7 | = 12 added like terms

| x - 7 | = 2 divided both sides by 6

x - 7 = 2 or x - 7 = -2 removed absolute value sign

x = 9 or x = 5 added 7 to both sides of both equations
