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

the least common multiple of the denominators is 6, so multiply everything by 6:
4a+3=6a-1
4=2a
a=2

Answer 2

the LCD is 6, so multiply both sides by 6 thus getting 4a+3=6a-1
6a-4a=3+1
2a=4
a=2

Answer 3

Thanks.

Answer 4

you are welcome.
