The expression we have to evaluate is:
[tex]2x+15-9[/tex]and we need to substitute the value of x = 8:
[tex]2(8)+15-9[/tex]Next, we solve the multiplication between 2 and 8, which is equal to 16:
[tex]16+15-9[/tex]And finally we add and substract the corresponding terms:
[tex]16+15-9=22[/tex]Answer: 22
