## anonymous 5 years ago I need help with this problem: 2a/3a-b = c solve for a

1. anonymous

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.

2. anonymous

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

3. anonymous

?

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.

$a=\frac{b c}{3 c-2}$
