Answer 2

Answer:

The solution set of equation 2x+y=23 is as follows:

If x=5 then

2×5+y=23

10+y=23

y=23−10

y=13

If x=7 then

2×7+y=23

14+y=23

y=23−14

y=9

The required points are (5,13),(7,9).

Also, the solution set of equation 4x−y=19 is as follows:

If x=5 then

4×5−y=19

20−y=19

−y=19−20

y=1

If x=7 then

4×7−y=19

28−y=19

−y=19−28

y=9

The required points are (5,1),(7,9).

Plot all the above points in the graph. Since the point of intersection in the graph is (7,9).

Hence the solution is x=7,y=9.
