15 Which ordered pair is the solution to this system of equations?
y = x + 4
x + y = 2
A (1,5)
B (0,2)
C (-1,3)
D (-4,0)

answer is c

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
