0.54x+4.4=y
Swap sides so that all variable terms are on the left hand side.
0.54x=y-4.4
Subtract 4.4 from both sides.
\frac{0.54x}{0.54}=\frac{y-4.4}{0.54}
Divide both sides of the equation by 0.54, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y-4.4}{0.54}
Dividing by 0.54 undoes the multiplication by 0.54.
x=\frac{50y-220}{27}
Divide y-4.4 by 0.54 by multiplying y-4.4 by the reciprocal of 0.54.
