+5

Okay, let's divide this problem up.

 

2x+5>10

 

Subtract 5 from both sides...

 

2x>5

 

Divide by 2 on each side...

 

x>2.5

 

This means that we know that x is greater than 2.5. Next, let's do 5x-4<20.

 

5x-4<20

 

Add 4 to each side...

 

5x<24

 

Divide by 5 on each side...

 

x<4.8

 

This means that x is less than 4.8.

 

Now we know that x is greater than 2.5, but less than 4.8.

 

2.5<x<4.8.

 

In conclusion, x can be any number from 2.5 to 4.8.
