180cm-m_{8}cm=0
Subtract 1m_{8}cm from both sides.
\left(180m-m_{8}m\right)c=0
Combine all terms containing c.
\left(180m-mm_{8}\right)c=0
The equation is in standard form.
c=0
Divide 0 by 180m-m_{8}m.
180cm-m_{8}cm=0
Subtract 1m_{8}cm from both sides.
\left(180c-m_{8}c\right)m=0
Combine all terms containing m.
\left(180c-cm_{8}\right)m=0
The equation is in standard form.
m=0
Divide 0 by 180c-m_{8}c.
