2x=y+1.6
The equation is in standard form.
\frac{2x}{2}=\frac{y+1.6}{2}
Divide both sides by 2.
x=\frac{y+1.6}{2}
Dividing by 2 undoes the multiplication by 2.
x=\frac{y}{2}+\frac{4}{5}
Divide y+1.6 by 2.
y+1.6=2x
Swap sides so that all variable terms are on the left hand side.
y=2x-1.6
Subtract 1.6 from both sides.
