Question

find a condition of linear equation graphically and verify the solution algebraically. 1}. x+y=2 ; 2x-y=5​

Answer 1

Answer:

x+y=2; 2x-y=5

Step-by-step explanation:

y=2-x......(1)

2x-y=5.....(2)

now put value of y in equation (2)

2x-y=5

2x-2-x=5

x=7

put value of x=7 in equation (1)

y=2-x

y=2-7

y=-5

so,(x,y)=(7,-5)
