Re: Equations With Fractions

Put the x's on one side and everything else on the other:

x/10 + 2x/10 = -1/5 + 3/5

Simplify:

3x/10 = 2/5
3x = 20/5 = 4
x = 4/3

The key is that to add or subtract fractions, you need a common denominator. Once you can combine all the fractions, it becomes simple to solve.
