Question

(1) x + y = 6 ; x - y = 4
(3) x + y = 0 ; 2x - y = 9​

Answer 1

1). x=5 ,y=1
3) x=3, y= -3

Answer 2

Answer:

(1): x=5 and y=1

Step-by-step explanation:

(1) x + y = 6 ....(1)

x - y = 4 ....(2)

subtracting eq 2 from eq 1, we get

x + y -( x - y) = 6 - 4

2y = 2

y = 1

substituting this value in eq 1

x + y = 6

x + 1 = 6

x = 6-1

x = 5

hence, x = 5 and y = 1
