2\times 2\left(x+1\right)=5\left(x+1\right)-6
Multiply both sides of the equation by 6, the least common multiple of 3,6.
4\left(x+1\right)=5\left(x+1\right)-6
Multiply 2 and 2 to get 4.
4x+4=5\left(x+1\right)-6
Use the distributive property to multiply 4 by x+1.
4x+4=5x+5-6
Use the distributive property to multiply 5 by x+1.
4x+4=5x-1
Subtract 6 from 5 to get -1.
4x+4-5x=-1
Subtract 5x from both sides.
-x+4=-1
Combine 4x and -5x to get -x.
-x=-1-4
Subtract 4 from both sides.
-x=-5
Subtract 4 from -1 to get -5.
x=5
Multiply both sides by -1.
