28x=1900-33y
Subtract 33y from both sides.
\frac{28x}{28}=\frac{1900-33y}{28}
Divide both sides by 28.
x=\frac{1900-33y}{28}
Dividing by 28 undoes the multiplication by 28.
x=-\frac{33y}{28}+\frac{475}{7}
Divide 1900-33y by 28.
33y=1900-28x
Subtract 28x from both sides.
\frac{33y}{33}=\frac{1900-28x}{33}
Divide both sides by 33.
y=\frac{1900-28x}{33}
Dividing by 33 undoes the multiplication by 33.
