9.4x=99-y
Subtract 1y from both sides.
\frac{9.4x}{9.4}=\frac{99-y}{9.4}
Divide both sides of the equation by 9.4, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{99-y}{9.4}
Dividing by 9.4 undoes the multiplication by 9.4.
x=\frac{495-5y}{47}
Divide 99-y by 9.4 by multiplying 99-y by the reciprocal of 9.4.
1y=99-9.4x
Subtract 9.4x from both sides.
y=-9.4x+99
