y=6000x+320000-8000x
Use the distributive property to multiply 8000 by 40-x.
y=-2000x+320000
Combine 6000x and -8000x to get -2000x.
-2000x+320000=y
Swap sides so that all variable terms are on the left hand side.
-2000x=y-320000
Subtract 320000 from both sides.
\frac{-2000x}{-2000}=\frac{y-320000}{-2000}
Divide both sides by -2000.
x=\frac{y-320000}{-2000}
Dividing by -2000 undoes the multiplication by -2000.
x=-\frac{y}{2000}+160
Divide y-320000 by -2000.
y=6000x+320000-8000x
Use the distributive property to multiply 8000 by 40-x.
y=-2000x+320000
Combine 6000x and -8000x to get -2000x.
