Question

2ab+4=d;a

Answer 1

Are we solving for a?

Answer 2

yes

Answer 3

Ok. So we have the equation..

2ab+4=d

We will first subtract the 4 on both sides..
2ab+4=d
-4 -4
---------
2ab=d-4

Now that we have taken a small step in this process, we now have the new equation of..
2ab=d-4

Now, this step is a little tricky to figure out. Most people tend to divide one number or variable at a time. But notice that you can not divide again and again in this. Thus, we shall divide by two; 2b.

2ab=d-4
2ab/2b=d-4/2b

a=d-4/2b
