28x+36>5\left(5+2x\right)
Use the distributive property to multiply 4 by 7x+9.
28x+36>25+10x
Use the distributive property to multiply 5 by 5+2x.
28x+36-10x>25
Subtract 10x from both sides.
18x+36>25
Combine 28x and -10x to get 18x.
18x>25-36
Subtract 36 from both sides.
18x>-11
Subtract 36 from 25 to get -11.
x>-\frac{11}{18}
Divide both sides by 18. Since 18 is positive, the inequality direction remains the same.
