Question

ASAP HELP ME IM STUCK​

Answer 1

Answer:

x=2

SK=21

KY=13

SY=34

Step-by-step explanation:

finding x:

SK+KY=SY

13x-5+2x+9=36-x

get x by itself

13x+2x+1x=36+5-9

simplify

16x=32

divide by 16 on both sides

x=2

Now plug in x (2) into the separate formulas

SK:

13(2)-5

26-5

21

KY:

2(2)+9

4+9

13

SY:

36-(2)

34

To double check your answer plug in what you got

SK+KY=SY

21+13=SY

34

and we got 34 above so this is correct.
