adding both equations simply

3x + x + y -y = 13 +3

4x =16

(x= 4)

now putting value of x in x-y =3

4 - y=3

(y= 1)

Answer 2

Answer:

1. x=4,y=1
2. Step-by-step explanation:
3. adding equations1&2
4. 3x+x+y-y=13+3
5. 4x=16
6. x=4
7. now putting the value of x in equation 2
8. 4-y=3
9. y=4-3
10. y=1

• :-x=4,y=1
