Answer:

x = -1 , y= 7

Step-by-step explanation:

3х + у = 4 .....equation 1

2x + y= 5 ....equation 2

Solving using linear combination method:

---------------------------------------------------------------

3х + у = 4

-2x - y = -5

-------------------...........Here the y cancels out.

x = -1

if x = -1

2x + y= 5

2(-1) + y = 5

y = 5 + 2

y = 7
