I know that "Not so old" is trying to be helpful to your long-term interests by just giving you the workings, but I suspect what you'd really like is for someone to give you the answers too, to save you trouble.

I make them as follows:

4. X=36

5. X=32

10. X=550

12. X=36

22. 78 (74+76+78 = 228)

24. 111 (110+112 = 222)

29. 38 (30+32+34+36+38 = 170)

37. X=250

Answer 2

If you can solve equations, try these:

4.  X/2 - 64 = -46

5.  5X - 98 = 62

10.  X/2 = 165 + X/5

12.  X/3 - 27 = -15

22.  X + (X + 1) + (X + 2) = 228

24.  X + (X+2) = 222  find X + 1

29.  X + (X+1) + (X + 2) + (X +3) + (X+ 4) = 170  find X+4

37.  X + 2X = 750

Have fun.
