TayTay1213 2 years ago find two consecutive integers whose sum is 35

1. Dido525

|dw:1352068849883:dw|

2. TayTay1213

can you write that in an equation so i can right it like that on my paper

3. SSmaths

17 + 18

4. Dido525

@SSmaths : Don't just give the answer...

5. Dido525

@TayTay1213 : I am saying 1 interger is x. If they are consecutive, the next term must be x+1

6. TayTay1213

im confused on how to do that

7. Dido525

|dw:1352069045322:dw|

8. Dido525

You follow?

9. TayTay1213

not really

10. SSmaths

sorry

11. Dido525

I am just saying that the interger we are trying to find is x.

12. Dido525

Do you get that?

13. Dido525

I am just assigning a variable.

14. Dido525

I am saying that integer we are trying to find is x.

15. TayTay1213

I get it so would it be like 17+(17+1)=35 so x would equal 17

16. Dido525

But we are trying to find x. We aren't given what x is.

17. Dido525

Wait. Have you even learnt algebra yet?

18. TayTay1213

well we are learning how to but i cant remember doing this

19. Dido525

The idea is that if you don't know what something is you say it's equal to x.

20. Dido525

so we don't know what the integer is so we say it's equal to x. Do you follow?

21. TayTay1213

yeah but how do you right that out

22. Dido525

Let one of the integers be= x

23. Dido525

That means the other integer must be = x+1 They are consecutive, meaning they come after one another.

24. Dido525

Together those two must add to 35.

25. TayTay1213

so would it be like x+(x+1)=35 and x=17

26. SSmaths

from that equation you have to re-arrange it to make x the subject

27. TayTay1213

can someone show me how to write it out

28. SSmaths

the equation can be written as x+x+1=35 then simplify from there

29. Dido525

So you get 2x+1 = 35 34=2x
