lawyer [7]3 years ago
8 0

Answer:

15, -7 x=15 y=-7

Step-by-step explanation:

x+y=8, we'll come back to this

x-y=22, move y to the other side, x=y+22

now insert the value of x =(y+22) to the other equation like so, (y+22)+y=8, simplify

2y+22=8 2y=(-14), y=(-7)

Insert the value of y into the first equation again like so, x+(-7)=8, simplify

x=15

15, -7
