Step-by-step explanation:
X+y=14-----(1)
X-y=4------(2)
From EQ(1)
X+y=14
Put x=0
0+y=14
Y=14
Put y=1
X+1=14
X=14-1
X=13
From EQ (2)
X-y=4
Put x=0
0-y=4
-y=4
Y=-4
Put y=1
X-1=4
X=4+1
X=5
From EQ (1) we get values of x and y as 13and 14 respectively and from eq (2) we get valued of x and y as 5 and (-4) respectively.
Graphically representation of the two EQ is...
