20y-5x=5\left(y+1\right)-2\left(x-\frac{1}{2}\right)
Use the distributive property to multiply 5 by 4y-x.
20y-5x=5y+5-2\left(x-\frac{1}{2}\right)
Use the distributive property to multiply 5 by y+1.
20y-5x=5y+5-2x+1
Use the distributive property to multiply -2 by x-\frac{1}{2}.
20y-5x=5y+6-2x
Add 5 and 1 to get 6.
20y-5x+2x=5y+6
Add 2x to both sides.
20y-3x=5y+6
Combine -5x and 2x to get -3x.
-3x=5y+6-20y
Subtract 20y from both sides.
-3x=-15y+6
Combine 5y and -20y to get -15y.
-3x=6-15y
The equation is in standard form.
\frac{-3x}{-3}=\frac{6-15y}{-3}
Divide both sides by -3.
x=\frac{6-15y}{-3}
Dividing by -3 undoes the multiplication by -3.
x=5y-2
Divide -15y+6 by -3.
20y-5x=5\left(y+1\right)-2\left(x-\frac{1}{2}\right)
Use the distributive property to multiply 5 by 4y-x.
20y-5x=5y+5-2\left(x-\frac{1}{2}\right)
Use the distributive property to multiply 5 by y+1.
20y-5x=5y+5-2x+1
Use the distributive property to multiply -2 by x-\frac{1}{2}.
20y-5x=5y+6-2x
Add 5 and 1 to get 6.
20y-5x-5y=6-2x
Subtract 5y from both sides.
15y-5x=6-2x
Combine 20y and -5y to get 15y.
15y=6-2x+5x
Add 5x to both sides.
15y=6+3x
Combine -2x and 5x to get 3x.
15y=3x+6
The equation is in standard form.
\frac{15y}{15}=\frac{3x+6}{15}
Divide both sides by 15.
y=\frac{3x+6}{15}
Dividing by 15 undoes the multiplication by 15.
y=\frac{x+2}{5}
Divide 6+3x by 15.
