4\left(2x-1\right)-3\left(x-1\right)+180=0
Multiply both sides of the equation by 12, the least common multiple of 3,4.
8x-4-3\left(x-1\right)+180=0
Use the distributive property to multiply 4 by 2x-1.
8x-4-3x+3+180=0
Use the distributive property to multiply -3 by x-1.
5x-4+3+180=0
Combine 8x and -3x to get 5x.
5x-1+180=0
Add -4 and 3 to get -1.
5x+179=0
Add -1 and 180 to get 179.
5x=-179
Subtract 179 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-179}{5}
Divide both sides by 5.
x=-\frac{179}{5}
Fraction \frac{-179}{5} can be rewritten as -\frac{179}{5} by extracting the negative sign.
