4\left(x-4\right)+3\left(2x-3\right)=6\times 3x-2\left(2x-3\right)
Multiply both sides of the equation by 12, the least common multiple of 3,4,2,6.
4x-16+3\left(2x-3\right)=6\times 3x-2\left(2x-3\right)
Use the distributive property to multiply 4 by x-4.
4x-16+6x-9=6\times 3x-2\left(2x-3\right)
Use the distributive property to multiply 3 by 2x-3.
10x-16-9=6\times 3x-2\left(2x-3\right)
Combine 4x and 6x to get 10x.
10x-25=6\times 3x-2\left(2x-3\right)
Subtract 9 from -16 to get -25.
10x-25=18x-2\left(2x-3\right)
Multiply 6 and 3 to get 18.
10x-25=18x-4x+6
Use the distributive property to multiply -2 by 2x-3.
10x-25=14x+6
Combine 18x and -4x to get 14x.
10x-25-14x=6
Subtract 14x from both sides.
-4x-25=6
Combine 10x and -14x to get -4x.
-4x=6+25
Add 25 to both sides.
-4x=31
Add 6 and 25 to get 31.
x=\frac{31}{-4}
Divide both sides by -4.
x=-\frac{31}{4}
Fraction \frac{31}{-4} can be rewritten as -\frac{31}{4} by extracting the negative sign.
