9x-26=4\left(x-12x+36\right)
Multiply both sides of the equation by 2.
9x-26=4\left(-11x+36\right)
Combine x and -12x to get -11x.
9x-26=-44x+144
Use the distributive property to multiply 4 by -11x+36.
9x-26+44x=144
Add 44x to both sides.
53x-26=144
Combine 9x and 44x to get 53x.
53x=144+26
Add 26 to both sides.
53x=170
Add 144 and 26 to get 170.
x=\frac{170}{53}
Divide both sides by 53.
