Given:-
- how do you graph 2x+y=3
To find:-
- Value of xy
Solution:-
Consider y as 1
- 2x+y=3
- 2x=3-1
- 2x=2
- x=2/2
- x=1 (required answer)
Hey mate value if xy is 1.
Explanation:-
- First of all any variable alone can be replaced with 1.
- So now 1 has its sign shown before it so when +1 moved to R.H.S. it will be 3-1.
- So now the difference is 2.
- Now multiplication will change to division i.e., 2/2.
- Now on division it will give 1 as quotient.
Varifying:-
Put 1 in place of xy.
- 2×1+1=3
- =>2+1=3
- =>3=3
- 0=0
L.H.S.=R.H.S.
hence proved!

Answer:
Here is the step by step solution...
Step-by-step explanation:
- make a table
2. assume x=0 , x=1 , x=2
3. x 0 1 2
y
4. Now replace x=0 in 2x+y=3
2(0)+y=3
y=3
5. Now replace x=1
2(1)+y=3
y=3-2
y= 1
6. Now replace x=2
2(2)+y=3
y=3-4
y= (-1)
complete the table...
x 0 1 2
y 3 1 -1
(0,3) ; (1,1) ; (2,-1)
Now you can plot the dots and make graph...
