Question

Write an equivalent expression by distributing the "-−" sign outside the parentheses: -(7n+0.9)

Answer 1

(-7n-0.9)
-7n-0.9=0
-7n=0.9
-n=7.78
n=7.78

Answer 2

-7n - .9

Explanation:

By distributing the - to the parentheses, you must add a - sign to each number in the parentheses. This makes the positives turn negative.
