Question

help! solve..

x+2 3-x 2
____ + _____ = ___
15 5 3

Answer 1

$$\large {
\cfrac{x+2}{15}+\cfrac{3-x}{5}=\cfrac{2}{3}
}
$$
if you were to multiply both sides by "15", what would it give you?

Answer 2

jdoe gave you a good idea. multiply both sides (all terms) by 15 like this:
\[ 15 \cdot \cfrac{x+2}{15}+15 \cdot\cfrac{3-x}{5}=15 \cdot\cfrac{2}{3} \]

can you simplify that ?
