180n-360=140n
Variable n cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by n.
180n-360-140n=0
Subtract 140n from both sides.
40n-360=0
Combine 180n and -140n to get 40n.
40n=360
Add 360 to both sides. Anything plus zero gives itself.
n=\frac{360}{40}
Divide both sides by 40.
n=9
Divide 360 by 40 to get 9.
