Answer:

x = 4

Explanation:

The ages now are 5x and 7x.

The ages in 4 years are 5x + 4 and 7x + 4.

5x + 4 + 7x + 4 = 56

12x + 8 = 56

12x = 48

x = 4

4

Explanation:

Given

Age of Roony = 5x

Age of Herald = 7x

After four years —

Age of Roony = (5x + 4)

Age of Herald = (7x + 4)

Now, According to the question

(5x + 4) + (7x + 4) = 56

→ 12x + 8 = 56

→ 12x = 56 - 8

→ 12x = 48

→ x = 4

Hope it helps you (`▿▿▿▿´ƪ)
