7\left(5x-6\right)>4\left(x+5\right)
Multiply both sides of the equation by 28, the least common multiple of 4,7. Since 28 is positive, the inequality direction remains the same.
35x-42>4\left(x+5\right)
Use the distributive property to multiply 7 by 5x-6.
35x-42>4x+20
Use the distributive property to multiply 4 by x+5.
35x-42-4x>20
Subtract 4x from both sides.
31x-42>20
Combine 35x and -4x to get 31x.
31x>20+42
Add 42 to both sides.
31x>62
Add 20 and 42 to get 62.
x>\frac{62}{31}
Divide both sides by 31. Since 31 is positive, the inequality direction remains the same.
x>2
Divide 62 by 31 to get 2.
