Question

Please solve this question.

Answer 1

GIVEN

2x + y = 10 eq.01

4x - y = 8 eq.02

TO FIND :- Solution by Graphical Method

SOLUTION

We will be equating both the equation for value of y interms of x

Then we will be putting appropriate vales for x and cordinally we can find value of y in tabular form separately for each equation.

Then we will be plotting the points in a graph joining them for forming a straight line for each equation. Hence two lines will be plotted in cardinal plane.

The point where both the lines get intersect is the answer.

Here the solution of the equations is (3,4)

And the testing whether (1,-4) lie on the equations or not we will be putting value in both equations.

(GIVEN IN ATTACHMENT)

1, -4 lies only on 2nd equation but not in the first.
