Would be very grateful if someone could help me!

Hi there’ I’d like help with the following math questions. Anything is accepted and acceptable. You don’t have to answer all the questions, I just want to know, learn and understand the basics of these questions. Anyone who helps, Thanks in Advance :]

[Solve to find variable]
1) h – (-8) =3

2) x – 9 = -20

3) -10 = w – 32 + 6

4) 6y = -15

5) 10y + 8y = 15

6) 35 = -2x – 15

7) 13 = 5 – 8m
36 – x = -36

9) 3 – 4d = 13

10) 14p – 8 22 + 20p

11) 12r – 18 = 13r + 18

12) -x – 1 = x – 21

13) 9y – 1 = y – 25

14) 5t – 26 = 18t

15) -15v – 40 = 23 – 8v

16) x / 2 + 2x / 3 = 5

17) 9x / 5 – 3x / 2 = 6

18) 2t + 2 / 3 – 5t / 4 = 11/6

19) 3k – 8 / 14 + 5/7 = k +1 / 2

Thanks Again to Helpers ^_^

not with the help of a calculator.
placing things and asking the child to count after adding or removing is pretty tedious. she s 6 yr old. how will she do addition and carry over questions like adding 29+44 with candies?

I’m in year 10 in Australia and looking for some websites that provide extra questions about maths, I’m falling back a bit and need to study a bit more, I don’t need extra tutors or leaning stuff like that, just websites that have more questions.

If you know of any, your help would be greatly appreciated
