5x-3x-1-2\left(4-3x\right)=x+6
To find the opposite of 3x+1, find the opposite of each term.
2x-1-2\left(4-3x\right)=x+6
Combine 5x and -3x to get 2x.
2x-1-8+6x=x+6
Use the distributive property to multiply -2 by 4-3x.
2x-9+6x=x+6
Subtract 8 from -1 to get -9.
8x-9=x+6
Combine 2x and 6x to get 8x.
8x-9-x=6
Subtract x from both sides.
7x-9=6
Combine 8x and -x to get 7x.
7x=6+9
Add 9 to both sides.
7x=15
Add 6 and 9 to get 15.
x=\frac{15}{7}
Divide both sides by 7.
