7x+14014z=630
Swap sides so that all variable terms are on the left hand side.
7x=630-14014z
Subtract 14014z from both sides.
\frac{7x}{7}=\frac{630-14014z}{7}
Divide both sides by 7.
x=\frac{630-14014z}{7}
Dividing by 7 undoes the multiplication by 7.
x=90-2002z
Divide 630-14014z by 7.
7x+14014z=630
Swap sides so that all variable terms are on the left hand side.
14014z=630-7x
Subtract 7x from both sides.
\frac{14014z}{14014}=\frac{630-7x}{14014}
Divide both sides by 14014.
z=\frac{630-7x}{14014}
Dividing by 14014 undoes the multiplication by 14014.
z=-\frac{x}{2002}+\frac{45}{1001}
Divide 630-7x by 14014.
