Answer:
x = -3 and x = -11
Step-by-step explanation:
Find the "bare" absolute value function, then solve the two resulting equations.
2|x+7| -3 = 5
2|x +7| = 8 . . . . . add 3
|x +7| = 4 . . . . . . divide by 2
This resolves to two equations:
x +7 = 4
x = -3 . . . . . subtract 7
and
x +7 = -4
x = -11 . . . . . subtract 7
The two solutions are ...
x = -3 and x = -11
