5x-10+5\left(3-y\right)=-\frac{11}{2}
Use the distributive property to multiply 5 by x-2.
5x-10+15-5y=-\frac{11}{2}
Use the distributive property to multiply 5 by 3-y.
5x+5-5y=-\frac{11}{2}
Add -10 and 15 to get 5.
5x-5y=-\frac{11}{2}-5
Subtract 5 from both sides.
5x-5y=-\frac{21}{2}
Subtract 5 from -\frac{11}{2} to get -\frac{21}{2}.
5x=-\frac{21}{2}+5y
Add 5y to both sides.
5x=5y-\frac{21}{2}
The equation is in standard form.
\frac{5x}{5}=\frac{5y-\frac{21}{2}}{5}
Divide both sides by 5.
x=\frac{5y-\frac{21}{2}}{5}
Dividing by 5 undoes the multiplication by 5.
x=y-\frac{21}{10}
Divide -\frac{21}{2}+5y by 5.
