Question

find the solution of the pair of linear equations by graphical metod. 2x+y=8,x+y=5.​

Answer 1

Step-by-step explanation:

x+y = 5

x = 5-y

2x+y = 8

(substitute 5-y instead of x on the following equation)

2(5-y)+y = 8

10-2y+y = 8

10-y = 8

-y = 8-10

-y = -2

y = 2

x+y = 5

x+2 = 5

x = 3

so x = 3

y = 2
