Question

A number,n,is added to 15 less than 3 times itself.result is 101. Wich equation can be used to find the value of x

Answer 1

Let the number be 'x'

According to the question,

A number is added to 15 less than 3 times itself.

So, x + (15 less than 3 times itself)

15 less than 3 times itself =
`3x - 15`

Now, x + (15 less than 3 times itself) =
`x + (3x-15)`

We get the result as 101.

So,
`x+ 3x-15 = 101`

`4x - 15 = 101`

Therefore, it is the required equation used to evaluate the number 'x'.
