Question

Sanjeev has few marbles he bought some more marbles and now he four times the number marbles he had initially hr lost 5 marbles and then his friend gave him 6 marbles write algebraic expression for the marbles he currently has if Sanjeev had 3 marbles initially what is the number of marbles he has now.

Answer 1

Answer: There are 10 marbles that is with Sanjeev now.

And algebraic expression for the marbles is given by

$3+x=13$

Step-by-step explanation:

Since we have given that

Number of marbles Sanjeev had = 3

Let the number of marbles he bought later on be 'x'.

According to question, we get that now he has 4 times the number of marbles he had initially:

$3+x=4\times 3\\\\3+x=12\\\\x=12-3\\\\x=9$

Now, Number of marbles he lost = 5

So, Number of marbles becomes,

$9-5=4$

Number of marbles his friend gave him = 6

So, Number of marbles he has now is given by

$4+6=10$

Hence, there are 10 marbles that is with Sanjeev now.

And algebraic expression for the marbles is given by

$3+x=12-5+6\\\\3+x=13$
