4\left(5x+1\right)-9-\left(4x+3\right)-6\left(2x+1\right)=0
Multiply both sides of the equation by 12, the least common multiple of 3,4,12,2.
20x+4-9-\left(4x+3\right)-6\left(2x+1\right)=0
Use the distributive property to multiply 4 by 5x+1.
20x-5-\left(4x+3\right)-6\left(2x+1\right)=0
Subtract 9 from 4 to get -5.
20x-5-4x-3-6\left(2x+1\right)=0
To find the opposite of 4x+3, find the opposite of each term.
16x-5-3-6\left(2x+1\right)=0
Combine 20x and -4x to get 16x.
16x-8-6\left(2x+1\right)=0
Subtract 3 from -5 to get -8.
16x-8-12x-6=0
Use the distributive property to multiply -6 by 2x+1.
4x-8-6=0
Combine 16x and -12x to get 4x.
4x-14=0
Subtract 6 from -8 to get -14.
4x=14
Add 14 to both sides. Anything plus zero gives itself.
x=\frac{14}{4}
Divide both sides by 4.
x=\frac{7}{2}
Reduce the fraction \frac{14}{4} to lowest terms by extracting and canceling out 2.
