Solve:i)x+y=5ii)x-y=3iii)2x+y=7iv)3x-2y=0
1 answer:
Answer:
I) X+Y
when X=0
0+y=5
Y=5
When Y=0
X+0=5
X=5
(X,y)=(5,5)
(ii) X-Y=3
When X=0
0-Y=3
Y=-3
When Y=0
X-0=3
X=3
(X,Y)=(3,3(
(III) 2x+Y=7
when X=0
0+Y=7
Y=7
when Y=0
2x+0=7
2x=7
X=7/2 or 3.5
(X,Y)=(3.5,7)
(Iv)
3X-2Y=0
when X=0
0-2Y=0
-2Y=0
Y=0
When Y=0
3x-0=0
3X=0
X=0
