2x-2-3\left(x+2\right)<6\left(1+x\right)
Use the distributive property to multiply 2 by x-1.
2x-2-3x-6<6\left(1+x\right)
Use the distributive property to multiply -3 by x+2.
-x-2-6<6\left(1+x\right)
Combine 2x and -3x to get -x.
-x-8<6\left(1+x\right)
Subtract 6 from -2 to get -8.
-x-8<6+6x
Use the distributive property to multiply 6 by 1+x.
-x-8-6x<6
Subtract 6x from both sides.
-7x-8<6
Combine -x and -6x to get -7x.
-7x<6+8
Add 8 to both sides.
-7x<14
Add 6 and 8 to get 14.
x>\frac{14}{-7}
Divide both sides by -7. Since -7 is negative, the inequality direction is changed.
x>-2
Divide 14 by -7 to get -2.
