9x=8z
Multiply both sides of the equation by 72, the least common multiple of 8,9.
\frac{9x}{9}=\frac{8z}{9}
Divide both sides by 9.
x=\frac{8z}{9}
Dividing by 9 undoes the multiplication by 9.
9x=8z
Multiply both sides of the equation by 72, the least common multiple of 8,9.
8z=9x
Swap sides so that all variable terms are on the left hand side.
\frac{8z}{8}=\frac{9x}{8}
Divide both sides by 8.
z=\frac{9x}{8}
Dividing by 8 undoes the multiplication by 8.
