Solve the equation for A.
12AB + 7B = 5A

Please help, I am completely stuck.
Answered by Henry
12AB + 7B = 5A.
12AB - 5A = -7B.
A(12B - 5) = -7B.
Divide by (12B-5):
A = -(7B/(12B-5)).

I thought you couldn't just switch 5A and 7B like that?
Answered by Vin Mwale
12AB + 7B = 5A. 7B = 5A - 12AB, 7B =A(5 - 12B). Divide both sides by (5 - 12B) 7B/(5 - 12B) = A

Can you cancel out the B in your final answer?

Like make your final answer 7/5-12? which would equal to -1?

Since there are 2 variables and only 1 Eq, I have to solve for 1 variable in terms of the other.
