Answer 1

Dalai have 45 marbles.

Explanation:

Consider the provided information.

Dalai bought a few swirl marbles and divided it equally among four of her friends and her brother, Jake. while playing, Jake lost two marbles and has only 7 marbles at present.

Let x is the number of marbles Dalai have.

She divide x number of marbles into 5 equal part (Four of friend and her brother)

That means each of them have
`(x)/(5)` marbles.

Jake lost two marbles out of
`(x)/(5)` and now he has only 7 marbles,

This can be represented as:

`(x)/(5)-2=7`

Solve the equation for x.

`(x)/(5)=7+2`

`(x)/(5)=9`

`x=45`

Hence, Dalai have 45 marbles.
