Question

7 times a number equals 3 less than 5 times that number. What is the number?

Answer 1

Let the number be N

7N = 5 N - 3

N = -3 / 2

SO YOUR NUMBER IS -3/2

Answer 2

`-(3)/(2)`

Explanation:

Let x represent the number.

7 times the number would be
`7x`.

5 times the number would be
`5x`.

3 less than 5 times the number would be
`5x-3`.

Equate both expressions:

`7x=5x-3`

Let us solve for x.

`7x-5x=5x-5x-3`

`2x=-3`

`(2x)/(2)=-(3)/(2)`

`x=-(3)/(2)`

Therefore, the required number is
`-(3)/(2)`.
