77-3.5x=y
Swap sides so that all variable terms are on the left hand side.
-3.5x=y-77
Subtract 77 from both sides.
\frac{-3.5x}{-3.5}=\frac{y-77}{-3.5}
Divide both sides of the equation by -3.5, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y-77}{-3.5}
Dividing by -3.5 undoes the multiplication by -3.5.
x=-\frac{2y}{7}+22
Divide y-77 by -3.5 by multiplying y-77 by the reciprocal of -3.5.
