1) 2x+3=0 can be written as 2x+0y+3=0
Then, taking y=1,
2x=-3
X=-1.5

So the Sol. is (-1.5,1)

Now in such cases when a variable is multiplyed by zero, then for all values of the variable , the corresponding value of the other variable wud be same (ie. for all values of y in this case, x=-1.5)

So, five solutions can be (-1.5,1), (-1.5,2), (-1.5,0), (-1.5,5), (-1.5,3)......etc



2) x=y can be written as x-y+0=0
Then taking x=1,
-y=-1
Y=1

Then taking x=2
-y=-2
Y=2

Then taking x=3
-y=-3
Y=3

Then taking x=4,
-y=-4
Y=4

Then taking x=-1
-y=-(-1)
Y=-1

So, five solutions can be (1,1),(2,2),(3,3),(4,4),(-1,-1)....etc
