Answer 1

Peter's present age is 6 years and John's present age is 17 years.

let

Peter's age = x

John is 11 years older than Peter. Therefore,

• John's age = x + 11

In 5years time, John will be twice as old as peter. Therefore,

• 2(x + 5) = x + 11 + 5

Present age equation:

2(x + 5) = x + 16

2x + 10 = x + 16

2x - x = 16 - 10

x = 6

Therefore, Peter's present age is 6 years and John's present age is 17 years.

Answer 2

Answer:

peters age is 6, john is 17

Step-by-step explanation:

let peter age be x,

so johns age will be x + 11

in 5 years time,

peter will be x+5

john will be 2(x+5)

using simultaneous method,

2(x+5) = x+11+5

2x +10 = x + 16

x = 6

so peter now will be x = 6

john = x + 11 = 6 + 11 = 17

peters age is 6

john is 17
