Question

I need help with this problem: 2a/3a-b = c
solve for a

Answer 1

Multiply each side of the equation by (3a-b) to get rid of the left side denominator.
Divide both sides of the equation by 2 to leave "a" alone on the left side.

Answer 2

yeah but there is still an a on the right side..

Answer 3

?

Answer 4

over site. wait one.
Do step one and then multiply out the product c(3a-b) to get:
2 a = 3 a c - b c
Move 3ac from the right side to the left side.
Factor out a from the sum on the left and side.
-a (-2 + 3 c) = -b c
Now divide both sides by (-2+3c)
There will be a minus sign in front of a on the left hand side.
Multiply both sides of the equation by a minus 1 to get ride of the negative sign.

Answer 5

\[a=\frac{b c}{3 c-2} \]
