x-180=4x
Variable x cannot be equal to 180 since division by zero is not defined. Multiply both sides of the equation by 4\left(x-180\right), the least common multiple of 4,x-180.
x-180-4x=0
Subtract 4x from both sides.
-3x-180=0
Combine x and -4x to get -3x.
-3x=180
Add 180 to both sides. Anything plus zero gives itself.
x=\frac{180}{-3}
Divide both sides by -3.
x=-60
Divide 180 by -3 to get -60.
