3\left(5x+4\right)>72-4\left(x-2\right)
Multiply both sides of the equation by 24, the least common multiple of 8,6. Since 24 is positive, the inequality direction remains the same.
15x+12>72-4\left(x-2\right)
Use the distributive property to multiply 3 by 5x+4.
15x+12>72-4x+8
Use the distributive property to multiply -4 by x-2.
15x+12>80-4x
Add 72 and 8 to get 80.
15x+12+4x>80
Add 4x to both sides.
19x+12>80
Combine 15x and 4x to get 19x.
19x>80-12
Subtract 12 from both sides.
19x>68
Subtract 12 from 80 to get 68.
x>\frac{68}{19}
Divide both sides by 19. Since 19 is positive, the inequality direction remains the same.
