Answer 2

Solution

We have given two pair of linear equations and we have to find the value of x and y through graph.

For that firstly convert the Equation either in the form of x or y and then plot points into and obtained the coordinate . Put the coordinate into graph of both the Equation and we obtained a interesting point with the help of coordinate of both the Equation which will be our final solution.

➙2x+y=8------(1)

➙x+2y= 7------(2)

Taking first Equation

2x+y=8

➙y= 8-2x

At x=0

➙y=8

At x= 1

➙y= 6

We obtained the coordinates (0,8)&(1,6)

Now,plot the coordinates into the graph.

-----------------------------------------------------------

Taking second Equation

x+2y= 7

➙x=7-2y

At y=0

➙x= 7

At y=1

➙x= 5

Now,plot the coordinates (7,0)&(5,1) into the graph

After only the coordinates of both the Equation we obtained a straight line graph which intersect at the points (3,2).

Hence,the solution for the given pair of linear equations is x= 3 and y= 2.
