5x=420-7.2y
Subtract 7.2y from both sides.
5x=-\frac{36y}{5}+420
The equation is in standard form.
\frac{5x}{5}=\frac{-\frac{36y}{5}+420}{5}
Divide both sides by 5.
x=\frac{-\frac{36y}{5}+420}{5}
Dividing by 5 undoes the multiplication by 5.
x=-\frac{36y}{25}+84
Divide 420-\frac{36y}{5} by 5.
7.2y=420-5x
Subtract 5x from both sides.
\frac{7.2y}{7.2}=\frac{420-5x}{7.2}
Divide both sides of the equation by 7.2, which is the same as multiplying both sides by the reciprocal of the fraction.
y=\frac{420-5x}{7.2}
Dividing by 7.2 undoes the multiplication by 7.2.
y=-\frac{25x}{36}+\frac{175}{3}
Divide 420-5x by 7.2 by multiplying 420-5x by the reciprocal of 7.2.
