Question

2x + y = -2 ; 3x - y = 7​

Answer 1

Step-by-step explanation:

substract equation 1 by 2 n later substitute the value in equation 1 then we get the valu of x and y

Answer 2

Step-by-step explanation:

2x + y = -2 .(I)

3x - y = 7 (II)

Adding (I) and (II)

5x = 5

⇒4⇒4 x= 1

Putting the value of x in (I)

2 x 1 + y = -2

⇒⇒ 2 + y = -2

⇒⇒ y = - 4
