Step-by-step explanation:

It is given

3x−2y=4

We can also write it as  

2y=3x−4

y=  

2

3x−4

​

 

Substituting x=2 in the given equation  

y=  

2

3(2)−4

​

 

So we get  

y=  

2

6−4

​

 

y=  

2

2

​

 

By division

y=1

Substituting x=−2 in the given equation  

y=  

2

3(−2)−4

​

 

So we get  

y=  

2

−6−4

​

 

y=  

2

−10

​

 

By division  

y=−5

 

x 2     -2

y     1 -5

Now draw a graph using the points A(2,1) and B(-2,-5)

Join the points AB through a line and extend in both the directions

It is given

x+y−3=0

We can also write it as  

y=3−x

Substituting x=1 in the given equation

y=3−1 So we get  

y=2

Substituting x=−1 in the given equation  

y=3−(−1)

So we get

y=4

 

x     1    -1

y  2     4

Now draw a graph using the points C(1,2) and D(−1,4)

Join the points CD through a line and extend in both the directions.

Therefore the coordinates of the point where the two graph lines intersect is A(2,1)
