Question

The equation -7(u+3)=49 is solved in several steps below.

For each step, choose the reason that best justifies it

Answer 1

u = -25/7

Explanation:

-7(u + 3) = 4

-7u -21 = 4 (distribute the -7)

-7u = 25 (add 21 to get -7u by itself)

u = -25/7 (divide by -7 by both sides to find the value of u)
