Question

Solve for x. 4 | x - 7 | + 2 | x - 7 | = 12

Answer 1

Answer: x = 9, 5

Step-by-step 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
