Question

I forgot how to do these, and i don’t remember whether they have two answers or not.

Solve for d.

-7| d - 1 | = -11

Answer 1

=18/7

=−4/7

Explanation:

Divide both sides by -7

−7|−1|=−11

The negatives are canceled.

Simplify

|−1|=11/7

Split the problem into two cases: one positive and one negative

=18/7

=−4/7

Answer 2

D=-4/7, D= 18/7. Divide both sides by -7.
