Question

In the equation 6-A/4=-3, what would A be?

Answer 1

I don't know.  Let's solve it together.  Then we'll both know what 'A' is,
and PLUS, you'll know how to find it.

6 - A/4  =  -3

We want to get 'A' all by itself on one side of the equation,
and everything else on the other side.

Subtract  6  from each side:    - A/4  =  -9

Multiply each side by  4 :      -A  =  -36

Multiply each side by -1 :      A  =  36

Did you follow that ?

Answer 2

-a / 4 + 6 -6 = -3 - 6
-a / 4 * 4 = -9 * 4
-a = -36
a = 36
