x+y=5
×=5-y
if y=1
then x=4
p(1,4)
similarly,
q(0,5)
r(5,0)
plot the points and join the line
similarly,
for x+y=3
a(0,3)
b(3,0)
c(1,2)
plot a,b,c on graph and join the line
✅both the lines will intersect then that is unique ans. and the pt. is ans
,✅or both lines will be parallel then no solution
or both lines will concurrent has infinite solu.
