Solve for $$r$$: $$\frac{r-45}{2} = \frac{3-2r}{5}.$$

Hi, when you multiply both sides by 10, you get $$5(r-45)=2(3-2r)$$ because $$10 \div 2 = 5 \text{ and } 10 \div 5 = 2$$ .

When you expand the equation you should get $$5r-225=6-4r$$.

Moving the variables to one side and constants to another you get $$9r=231$$.

Dividing both sides by 9 gets us $$r= 231\div 9$$ which equals to $$25 \frac{2}{3}$$.
