135x=431-231y
Subtract 231y from both sides.
\frac{135x}{135}=\frac{431-231y}{135}
Divide both sides by 135.
x=\frac{431-231y}{135}
Dividing by 135 undoes the multiplication by 135.
x=-\frac{77y}{45}+\frac{431}{135}
Divide 431-231y by 135.
231y=431-135x
Subtract 135x from both sides.
\frac{231y}{231}=\frac{431-135x}{231}
Divide both sides by 231.
y=\frac{431-135x}{231}
Dividing by 231 undoes the multiplication by 231.
y=-\frac{45x}{77}+\frac{431}{231}
Divide 431-135x by 231.
