2\left(x-1\right)-\left(x+2\right)=3\times 4x
Multiply both sides of the equation by 6, the least common multiple of 3,6,2.
2x-2-\left(x+2\right)=3\times 4x
Use the distributive property to multiply 2 by x-1.
2x-2-x-2=3\times 4x
To find the opposite of x+2, find the opposite of each term.
x-2-2=3\times 4x
Combine 2x and -x to get x.
x-4=3\times 4x
Subtract 2 from -2 to get -4.
x-4=12x
Multiply 3 and 4 to get 12.
x-4-12x=0
Subtract 12x from both sides.
-11x-4=0
Combine x and -12x to get -11x.
-11x=4
Add 4 to both sides. Anything plus zero gives itself.
x=\frac{4}{-11}
Divide both sides by -11.
x=-\frac{4}{11}
Fraction \frac{4}{-11} can be rewritten as -\frac{4}{11} by extracting the negative sign.
