X=14
Y=-9

Answer 2

can you please tell me how you got that?

Answer 3

yes no problem

Answer 4

first you have to have y by its self in both expressions.
Y=5-X IS FINE
but 1=4X + 3Y has to be changed to -3Y=4X-1
THEN PLUG ONE IN TO THE OTHER
WHICH NOW ITS
-3(5-X)=4X-1
-15+3X=4X-1
NEXT
COMBINE LIKE TERMS
-15+1=4X-3X
-14=X
nOW ONCE YOU HAVE THAT PLUG IN TO THE OTHER EXPRESSION
Y=5-(-14)
Y=19

SO YOUR ANSWERS ARE X=-14 AND Y=19 SORRY WORTE IT WORNG THE FIRST TIME I GAVE YOU THE ANSWER
