Answer:

2<x<3

Explanation:

4x – 4 < 8 AND 9x + 5 > 23

Solve them separately and then put back together

4x – 4 < 8

Add 4 to each side

4x – 4+4 < 8+4

4x <12

Divide by 4

4x/4 <12/4

x <3

9x + 5 > 23

Subtract 5 from each side

9x+5-5 >23-5

9x>18

Divide each side by 9

9x/9 >18/9

x>2

2<x and x<3

2<x<3
