Question

Solve the equation. If there is no solution, select no solution. -2|h-7|=-28

A) no solution
B) h = 7, h = –21
C) h = –7, h = 21
D)h = 21, h = –21

Answer 1

C). h = –7, h = 21.

Explanation:

-2|h-7| = -28

Divide both sides by -2:

|h - 7| = 14

The vertical lines means the absolute value of h - 7. The h - 7 may be positive or negative so we have 2 equations:

h - 7 = 14

So h = 21.

and h - 7 = -14

so h = -7.
