3x-6-1>5x+9
Use the distributive property to multiply 3 by x-2.
3x-7>5x+9
Subtract 1 from -6 to get -7.
3x-7-5x>9
Subtract 5x from both sides.
-2x-7>9
Combine 3x and -5x to get -2x.
-2x>9+7
Add 7 to both sides.
-2x>16
Add 9 and 7 to get 16.
x<\frac{16}{-2}
Divide both sides by -2. Since -2 is negative, the inequality direction is changed.
x<-8
Divide 16 by -2 to get -8.
