7. x-3

8. - am not able to see the problem clearly to read it. I think it says 9 and b?? quotient of those would be 9/b.

9. you need to multiply the terms inside the equation by 2 first.

giving you 2x plus 8 and then subtract
[tex] {3}^{2} [/tex]
or 9

positive 8 minus 9 leaves negative 1.

so simplified...

2x - 1

10. same process as 9
5x + 2
