75x=100-80y
Subtract 80y from both sides.
\frac{75x}{75}=\frac{100-80y}{75}
Divide both sides by 75.
x=\frac{100-80y}{75}
Dividing by 75 undoes the multiplication by 75.
x=-\frac{16y}{15}+\frac{4}{3}
Divide 100-80y by 75.
80y=100-75x
Subtract 75x from both sides.
\frac{80y}{80}=\frac{100-75x}{80}
Divide both sides by 80.
y=\frac{100-75x}{80}
Dividing by 80 undoes the multiplication by 80.
y=-\frac{15x}{16}+\frac{5}{4}
Divide 100-75x by 80.
