0.6y=85-x
Subtract x from both sides.
\frac{0.6y}{0.6}=\frac{85-x}{0.6}
Divide both sides of the equation by 0.6, which is the same as multiplying both sides by the reciprocal of the fraction.
y=\frac{85-x}{0.6}
Dividing by 0.6 undoes the multiplication by 0.6.
y=\frac{425-5x}{3}
Divide 85-x by 0.6 by multiplying 85-x by the reciprocal of 0.6.
x=85-0.6y
Subtract 0.6y from both sides.
