1.3x+1.1=y
Swap sides so that all variable terms are on the left hand side.
1.3x=y-1.1
Subtract 1.1 from both sides.
\frac{1.3x}{1.3}=\frac{y-1.1}{1.3}
Divide both sides of the equation by 1.3, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y-1.1}{1.3}
Dividing by 1.3 undoes the multiplication by 1.3.
x=\frac{10y-11}{13}
Divide y-1.1 by 1.3 by multiplying y-1.1 by the reciprocal of 1.3.
