Question

find the solution of the following pair of linear equations by the graphical method
2x+y=8
x+y=5​

Answer 1

The solution for the pair of linear equation 2x+y=8 and x-y=1 is x = 3, y = 2

Step-by-step explanation:

Given linear equations

Which are the equations of a line

In order to draw the graph of a line we only need two points satisfying the equation of the line

The graphs of lines  and  are drawn

From graph it is clear that the lines intersect at point A

The coordinates of point A are (3,2)

Therefore, the solution of the pair of linear equations is

x = 3, y = 2
