Question

Solve the following pair of linear equations by graph method.

2x+y = 6 and 2x-y+2 = 0​

Answer 1

Answer:

3 and -1

Step-by-step explanation:

1 . 2x + y = 6

2 ( x + y) = 6

( x + y) = 6/3

( x + y) = 3

2 . 2x - y + 2 = 0

2 ( x - y) + 2 = 0

2 ( x - y) = 0 - 2

2 (x - y) = -2

(x - y) = -2/2

( x - y) = - 1
