Answer:

Step-by-step explanation:

Let Jire's age = x

Pamela's age = x - 12

Sum of their ages = 28

x + x - 12= 28

2x - 12 = 28

      2x = 28+12

      2x = 40

        x = 40/2

       x = 20

Jiri's age = 20 year

Given :-

  • No. of years Pamela younger = 12 years.

  • Sum of their ages.

To find:-

  • Jiri's age

Let :-

  • Pamela's age be x

  • Jiri's age be x+ 12

Explanation:

Sum of their ages is 28

Therefore equation formed be like :-

⇢ x + (x + 12) = 28

⇢ x + x + 12 = 28

⇢2x + 12 = 28

⇢2x = 28 - 12

⇢2x = 16

⇢ x = 16/2

⇢ x = 8

As we have taken Jiri's age as x + 12

Therefore

↣ 8 + 12

↣ 20

↣20 years
