# Math Help - Simplify

1. ## Simplify

Simplify
x-3/3-x-2/5

2. You have x - x -1 - 2/5

The x's cancel each other out, and then use a common denominator of 5:

= -5/5 - 2/5 = -7/5

Or did you mean (x-3)/3 - (x-2)/5 ?

The above means the following:

. . . . . $x\, -\, \frac{3}{3}\, -\, x\, -\, \frac{2}{5}$

If this is what you meant, then subtract the x's and then note that 3/3 = 1 = 5/5, and add the -5/5 and the -2/5.

If, on the other hand, you meant the following:

. . . . . $\frac{x\, -\, 3}{3}\, -\, \frac{x\, -\, 2}{5}$

...then you need to convert the two fractions to a common denominator:

. . . . . $\frac{5(x\, -\, 3)}{3\times 5}\, -\, \frac{3(x\, -\, 2)}{5\times 3}$

Multiply out, and then simplify across the top.
