Graphically
2x+y = 3
x + 3y = -1
Answers
hope it helps....
i dont have graph paper,
thats why i have not made graph paper
if i make it on any copy yuo will not be able to underatand
Answer:
First given,
2x+y=3
2x=3-y. Eqn.. 1
Now,
i) Put y=3 in eqn.. 1
2x=3-(3)
2x=0
x=0/2
x=0
ii) put y=1 in eqn.. 1
2x=3-(1)
2x=2
x=2/2
x=1
iii) put y=7 in eqn.. 1
2x=3-(7)
2x=-4
x=-4/2
x=-2
2)x+3y=-1
3y=-1-x. Eqn.. 2
Now,
i) put x=-1 in eqn.. 2
3y=-1-(-1)
3y=-1+1
3y=0
y=0/3
y=0
ii) put x=-4 in eqn. 2
3y=-1-(-4)
3y=-1+4.
3y=+3.
y=3/3
y=1
iii) put x=2 in eqn. 2
3y=-1-(2)
3y=-3
y=-3/3
y=-1
If we draw graph for first eqn. We get graph in I Quadrant and II Quadrant
For second eqn. We get graph in II Quadrant and IV Quadrant
