Answer 2

Answer:

He had 5 marbles at first.

Step-by-step explanation:

Given :

• His friend gave him 4 marbles

• He divided all the marbles among 7 boys. Each boy got 2 marbles.

Find:

• Marbles he had in start

Solution:

let, boy was having marbles = x

He doubled it by purchasing more marbles = 2x

His friend gave him 4 marbles = 2x + 4

He divided all the marbles among 7 boys. Each boy got 2 marbles. = 2x + 4 / 7 = 2

➨ 2x + 4 / 7 = 2

➨ 2x + 4 = 2 × 7

➨ 2x + 4 = 14

➨ 2x = 14 - 4

➨ 2x + 4 = 10

➨ x = 10 / 2

➨ x = 5

Therefore,

He had 5 marbles at first.
