4x=2.8-10y
Subtract 10y from both sides.
\frac{4x}{4}=\frac{2.8-10y}{4}
Divide both sides by 4.
x=\frac{2.8-10y}{4}
Dividing by 4 undoes the multiplication by 4.
x=-\frac{5y}{2}+\frac{7}{10}
Divide 2.8-10y by 4.
10y=2.8-4x
Subtract 4x from both sides.
\frac{10y}{10}=\frac{2.8-4x}{10}
Divide both sides by 10.
y=\frac{2.8-4x}{10}
Dividing by 10 undoes the multiplication by 10.
y=-\frac{2x}{5}+\frac{7}{25}
Divide 2.8-4x by 10.
