Question

Solve: 2a/3 + 1/2 = (6a-1)/6
I hit a mental block involving equations with fractions...somebody care to explain how to do this one?

Answer 1

Multiply each item on both sides of the equation by 6 in order to eliminate the denominators which gives you the following:

(2a)(2) + (1)(3) = 6a - 1
4a + 3 = 6a - 1
3 + 1 = 6a - 4a This is combining like terms
4 = 2a Rearranging this equation you get:
2a = 4
a = 2
