6x-4-5x+7\leq 2\left(x+1\right)
Use the distributive property to multiply 2 by 3x-2.
x-4+7\leq 2\left(x+1\right)
Combine 6x and -5x to get x.
x+3\leq 2\left(x+1\right)
Add -4 and 7 to get 3.
x+3\leq 2x+2
Use the distributive property to multiply 2 by x+1.
x+3-2x\leq 2
Subtract 2x from both sides.
-x+3\leq 2
Combine x and -2x to get -x.
-x\leq 2-3
Subtract 3 from both sides.
-x\leq -1
Subtract 3 from 2 to get -1.
x\geq \frac{-1}{-1}
Divide both sides by -1. Since -1 is negative, the inequality direction is changed.
x\geq 1
Divide -1 by -1 to get 1.
