4\left(x-2\right)+3\left(2x-5\right)>12x-5
Multiply both sides of the equation by 24, the least common multiple of 6,8,24. Since 24 is positive, the inequality direction remains the same.
4x-8+3\left(2x-5\right)>12x-5
Use the distributive property to multiply 4 by x-2.
4x-8+6x-15>12x-5
Use the distributive property to multiply 3 by 2x-5.
10x-8-15>12x-5
Combine 4x and 6x to get 10x.
10x-23>12x-5
Subtract 15 from -8 to get -23.
10x-23-12x>-5
Subtract 12x from both sides.
-2x-23>-5
Combine 10x and -12x to get -2x.
-2x>-5+23
Add 23 to both sides.
-2x>18
Add -5 and 23 to get 18.
x<\frac{18}{-2}
Divide both sides by -2. Since -2 is negative, the inequality direction is changed.
x<-9
Divide 18 by -2 to get -9.
