4\left(x+1\right)+6x-9-\left(2x-3\right)=2\left(1-1\right)
Multiply both sides of the equation by 12, the least common multiple of 3,2,4,12,6.
4x+4+6x-9-\left(2x-3\right)=2\left(1-1\right)
Use the distributive property to multiply 4 by x+1.
10x+4-9-\left(2x-3\right)=2\left(1-1\right)
Combine 4x and 6x to get 10x.
10x-5-\left(2x-3\right)=2\left(1-1\right)
Subtract 9 from 4 to get -5.
10x-5-2x-\left(-3\right)=2\left(1-1\right)
To find the opposite of 2x-3, find the opposite of each term.
10x-5-2x+3=2\left(1-1\right)
The opposite of -3 is 3.
8x-5+3=2\left(1-1\right)
Combine 10x and -2x to get 8x.
8x-2=2\left(1-1\right)
Add -5 and 3 to get -2.
8x-2=2\times 0
Subtract 1 from 1 to get 0.
8x-2=0
Multiply 2 and 0 to get 0.
8x=2
Add 2 to both sides. Anything plus zero gives itself.
x=\frac{2}{8}
Divide both sides by 8.
x=\frac{1}{4}
Reduce the fraction \frac{2}{8} to lowest terms by extracting and canceling out 2.
