13 ??

4. Nnesha

karen is 13 years older than juan let karen = x and juan =y so you can replace karen and juan with x and y x is 13 years older than y here is represent = sign

5. Nnesha

older than so means + sign x is 13 years + y replace is with equal sign

6. Nnesha

the sum is 55 again is represent equal sign sum/add so when you add their agez u should get 55 x+y=55

7. sbuck98

I need to find x and y though... @Nnesha

8. sbuck98

so 55-13?

9. sbuck98

can u help me with all 3?

10. Nnesha

$$\color{blue}{\text{Originally Posted by}}$$ @Nnesha older than so means + sign x is 13 years + y replace is with equal sign $$\color{blue}{\text{End of Quote}}$$ |dw:1443470989015:dw|

11. Nnesha

first equation x=13+y 2nd equation x+y=55 now solve for x and y

12. sbuck98

I keep getting 0.

13. Nnesha

$\huge\rm \color{ReD}{x=13+y}$$\huge\rm \color{ReD}{x}+y=55$ substitute x for 1st equation into 2nd

14. sbuck98

43

15. sbuck98

can you help with the other 2?

16. sbuck98

*42

17. Nnesha

42 is what ? show ur work

18. sbuck98

Y=42

19. Nnesha

how did you get that ?

20. sbuck98

rearranging and solving

21. sbuck98

and 42-13=55

22. Nnesha

42-13 isn't equal to 55

23. sbuck98

+

24. Nnesha

well 52+3 is also equal to 55

25. Nnesha

we don't know their age we can't say juan is 42 or karent is 42

26. sbuck98

what do I do now?

27. Nnesha

|dw:1443471837600:dw|

28. sbuck98

13+y=55 thats what im trying to solve

29. Nnesha

just substitute x with 13+y |dw:1443472032633:dw| the other y stay the same

30. Nnesha

now solve for y $\huge\rm 13+y+y=55$ first combine like terms

31. sbuck98

?

32. Nnesha

what ??

33. sbuck98

why are you using 3 ys?

34. sbuck98

2

35. Nnesha

|dw:1443472292016:dw| these are 2 equations

36. sbuck98

and the solution is 0 for the both.

37. Nnesha

|dw:1443472322681:dw|

38. Nnesha

i have no idea how u got 0 please show ur work so i can understand where u did a mistake .

39. sbuck98

please tell me how I am suppose to solve ot

40. Nnesha

solve for y $\huge\rm 13+y+y=55$ first combine like terms what are like terms at left side ?
