10y+10m=7x+657
Swap sides so that all variable terms are on the left hand side.
10m=7x+657-10y
Subtract 10y from both sides.
10m=7x-10y+657
The equation is in standard form.
\frac{10m}{10}=\frac{7x-10y+657}{10}
Divide both sides by 10.
m=\frac{7x-10y+657}{10}
Dividing by 10 undoes the multiplication by 10.
m=\frac{7x}{10}-y+\frac{657}{10}
Divide 7x+657-10y by 10.
7x=10y+10m-657
Subtract 657 from both sides.
\frac{7x}{7}=\frac{10y+10m-657}{7}
Divide both sides by 7.
x=\frac{10y+10m-657}{7}
Dividing by 7 undoes the multiplication by 7.
