307981-720x=1000y
Multiply 18 and 40 to get 720.
-720x=1000y-307981
Subtract 307981 from both sides.
\frac{-720x}{-720}=\frac{1000y-307981}{-720}
Divide both sides by -720.
x=\frac{1000y-307981}{-720}
Dividing by -720 undoes the multiplication by -720.
x=-\frac{25y}{18}+\frac{307981}{720}
Divide 1000y-307981 by -720.
307981-720x=1000y
Multiply 18 and 40 to get 720.
1000y=307981-720x
Swap sides so that all variable terms are on the left hand side.
\frac{1000y}{1000}=\frac{307981-720x}{1000}
Divide both sides by 1000.
y=\frac{307981-720x}{1000}
Dividing by 1000 undoes the multiplication by 1000.
y=-\frac{18x}{25}+\frac{307981}{1000}
Divide 307981-720x by 1000.
