4x-12=9x\times 3
Multiply both sides of the equation by 6, the least common multiple of 3,2.
4x-12=27x
Multiply 9 and 3 to get 27.
4x-12-27x=0
Subtract 27x from both sides.
-23x-12=0
Combine 4x and -27x to get -23x.
-23x=12
Add 12 to both sides. Anything plus zero gives itself.
x=\frac{12}{-23}
Divide both sides by -23.
x=-\frac{12}{23}
Fraction \frac{12}{-23} can be rewritten as -\frac{12}{23} by extracting the negative sign.
