Question

4= a/7 - 4 can anyone help find a ?

Answer 1

A = 28

Explanation:

You would multiply by 7 on both sides. You multiply by 7 on the right to get rid of the fraction, so you are just left with A on the right. Then you multiply on the left, so it would be 4x7, which equals 28. A=28.

Answer 2

56 =a

Explanation:

4 = a/7 -4

Add 4 to each side

4+4 = a/7 -4+4

8 = a/7

Multiply each side by 7

8*7 =a/7*7

56 =a
