Answer 1

Answer:

Anil's age is 48 years and sumeet's age is 39 years

Step-by-step explanation:

Let sumeet be x and anil be y

From the first condition,

x+9=y

x-y=-9......(1)

From the second condition,

2(x-10)=y+10

2x-20=y+10

2x-y=30.......(2)

Subtract (1) from (2)

2x-y=30

-

x-y=-9

_______

x+0=39

x=39

Put x=39 in (1)

39+9=y

y=48

I hope the answer will help you dear

Answer 2

Answer:

Sumit age : 39 yrs ;

Anil age : 48 yrs

Step by step explanation :

Let sumit be x years

sumit be x years=> Anil = x+9

sumit be x years=> Anil = x+9(x+9 )+10= 2 (x-10)

sumit be x years=> Anil = x+9(x+9 )+10= 2 (x-10)=> x+19 = 2x -20

sumit be x years=> Anil = x+9(x+9 )+10= 2 (x-10)=> x+19 = 2x -20=> x-2x = -20 -19

sumit be x years=> Anil = x+9(x+9 )+10= 2 (x-10)=> x+19 = 2x -20=> x-2x = -20 -19=> -x = -39

sumit be x years=> Anil = x+9(x+9 )+10= 2 (x-10)=> x+19 = 2x -20=> x-2x = -20 -19=> -x = -39=> x = 39

sumit be x years=> Anil = x+9(x+9 )+10= 2 (x-10)=> x+19 = 2x -20=> x-2x = -20 -19=> -x = -39=> x = 39Hence summit = 39 years and

sumit be x years=> Anil = x+9(x+9 )+10= 2 (x-10)=> x+19 = 2x -20=> x-2x = -20 -19=> -x = -39=> x = 39Hence summit = 39 years andAnil = 48 years
