3\left(2x-5\right)-\left(1+x\right)=6
Multiply both sides of the equation by 6, the least common multiple of 2,6.
6x-15-\left(1+x\right)=6
Use the distributive property to multiply 3 by 2x-5.
6x-15-1-x=6
To find the opposite of 1+x, find the opposite of each term.
6x-16-x=6
Subtract 1 from -15 to get -16.
5x-16=6
Combine 6x and -x to get 5x.
5x=6+16
Add 16 to both sides.
5x=22
Add 6 and 16 to get 22.
x=\frac{22}{5}
Divide both sides by 5.
