Question

please solve it..........................​

Answer 1

Answer:

2x=20,by addition of eq. 1 &2.

Step-by-step explanation:

Hence x is 10.

If x is 10 ,y will be 8

so the value of (x,y) is (10,8) & (10,8)

Answer 2

x+y=18--------(i)

x-y=2------------(ii)

In equation (i)

x+y=18

x=18-y

Put x=18-y in equation (ii)

18-y-y=2

18-2y=2

-2y=-20

x=10

Put x=10 in equation i

y+10=18

y=8

x=10,y=8
