A 20−pound bag of sugar costs (y + 3) dollars while a 10−pound package costs (y − 3) dollars. If the price per pound of sugar is the same for both packages, the equation below can be used to solve for y.
y+3/20 = y-3/10
What is the value, in dollars, of y?

We have
\[\frac{y+3}{20}=\frac{y-3}{10}\]
multiply both sides by 20, can you do it @rebecca1233 ?

\[20\times \frac{y+3}{20}=\frac{y-3}{10}\times 20\]
