Question

Bob is 3 years older than twice Johns age the sum of there is ages is 33 . How old is Bob ​

Answer 1

Answer:

Let Jack’s present age be’x’ years.

Therefore John’s present age will be’2x”

After 3 years, Jack’s age=x+3years

John’s age=2x+3 years.

The sum of their ages = 33 years

According to given condition th equation will be

x+3+2x+3 = 33

3x+6 =33

3x = 33–6

3x= 27

x= 27/3

x=9 years

Jack’s present age =x = 9 years

John’spresent age = 2x = 2×9 =18 years

Answer 2

Answer:

Bob is 23 years old

Step-by-step explanation:

Let bob be x

John be y

x= 2y+3  ------------------------- 1

x+y=33   ----------------------------- 2

x=33-y

substitute in 1

33-y = 2y+3

30=3y

y=10

substitute in 2

x+y=33

x+10=33

x=23
