1710\left(2x-1\right)+4\left(2x+3\right)=2\left(x+1\right)-\left(x-1\right)+9x
Multiply both sides of the equation by 12, the least common multiple of 2,3,6,12,4.
3420x-1710+4\left(2x+3\right)=2\left(x+1\right)-\left(x-1\right)+9x
Use the distributive property to multiply 1710 by 2x-1.
3420x-1710+8x+12=2\left(x+1\right)-\left(x-1\right)+9x
Use the distributive property to multiply 4 by 2x+3.
3428x-1710+12=2\left(x+1\right)-\left(x-1\right)+9x
Combine 3420x and 8x to get 3428x.
3428x-1698=2\left(x+1\right)-\left(x-1\right)+9x
Add -1710 and 12 to get -1698.
3428x-1698=2x+2-\left(x-1\right)+9x
Use the distributive property to multiply 2 by x+1.
3428x-1698=2x+2-x-\left(-1\right)+9x
To find the opposite of x-1, find the opposite of each term.
3428x-1698=2x+2-x+1+9x
The opposite of -1 is 1.
3428x-1698=x+2+1+9x
Combine 2x and -x to get x.
3428x-1698=x+3+9x
Add 2 and 1 to get 3.
3428x-1698=10x+3
Combine x and 9x to get 10x.
3428x-1698-10x=3
Subtract 10x from both sides.
3418x-1698=3
Combine 3428x and -10x to get 3418x.
3418x=3+1698
Add 1698 to both sides.
3418x=1701
Add 3 and 1698 to get 1701.
x=\frac{1701}{3418}
Divide both sides by 3418.
