Question

N is an integer:
-2 < 2n <8? What is the possible values of N.

How do I slove: 3y -2 >5

8x-3>6x+4

Also how do I solve the simultaneous equation:
3x- 2y =7
7x +2y =13.

If you could show me how to work them out it would be really helpful! :)

-2<2n<8 you add 2 tothe 8. So now its 2n<10. Then you divide by 2 on both sides so its n<5.
3y-2>5 you add 2 to the 5. So now its 3y>7 then divide by 3 on both sides. So y>2.3. And i dont remember the last ones. Its been so long since ive done these.
