Pretend the parenthesis are absolute value symbols.
(x+7) + 10 = 6
Is it a solution why or why not?
(x+7) + 10 = 6
Is it a solution why or why not?
-
|x+7| + 10 = 6
Subtract 10 from both sides:
|x+7| = -4
No. Absolute values are always positive.
Subtract 10 from both sides:
|x+7| = -4
No. Absolute values are always positive.
