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
X=4 ........................................
