`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
Nnesha
  • Nnesha
older than so means + sign `x is 13 years + y` replace is with equal sign
Nnesha
  • 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`
sbuck98
  • sbuck98
I need to find x and y though... @Nnesha
sbuck98
  • sbuck98
so 55-13?
sbuck98

  • Nnesha
first equation x=13+y 2nd equation x+y=55 now solve for x and y
sbuck98
  • sbuck98
I keep getting 0.
Nnesha
  • Nnesha
\[\huge\rm \color{ReD}{x=13+y}\]\[\huge\rm \color{ReD}{x}+y=55\] substitute x for 1st equation into 2nd

  • sbuck98
can you help with the other 2?

*42
Nnesha
  • Nnesha

sbuck98
  • sbuck98
Y=42
Nnesha
  • Nnesha
how did you get that ?
sbuck98
  • sbuck98
rearranging and solving
sbuck98
  • sbuck98
and 42-13=55
Nnesha
  • Nnesha
42-13 isn't equal to 55
sbuck98
  • sbuck98
+
Nnesha
  • Nnesha
well 52+3 is also equal to 55
Nnesha
  • Nnesha
we don't know their age we can't say juan is 42 or karent is 42
sbuck98

sbuck98
  • sbuck98
13+y=55 thats what im trying to solve
Nnesha
  • Nnesha
just substitute x with 13+y |dw:1443472032633:dw| the other y stay the same
Nnesha
  • Nnesha
now solve for y \[\huge\rm 13+y+y=55\] first combine like terms
sbuck98
  • sbuck98
?
Nnesha
  • Nnesha
what ??
sbuck98
  • sbuck98
why are you using 3 ys?
sbuck98
  • sbuck98
2
Nnesha
  • Nnesha
|dw:1443472292016:dw| these are 2 equations
sbuck98
  • sbuck98
and the solution is 0 for the both.
Nnesha
  • Nnesha
|dw:1443472322681:dw|
Nnesha

sbuck98
  • sbuck98
please tell me how I am suppose to solve ot
Nnesha
  • Nnesha
solve for y \[\huge\rm 13+y+y=55\] first combine like terms what are like terms at left side ?
