Question

If 10 times a number is increased by five the result is 12 less than nine times the number

Answer 1

Given:

The number is 10 times increased by five the result is 12 less than 9 times of number

Find-:

The number

Explanation-:

Let the number = x

The number is 10 times

`10x`

Increased by 5 units then number is:

`10x+5`

Then result increased by 9 times less then 12

So,

`10x+5=9x-12`

So, the number is:

`\begin{gathered} 10x+5=9x-12 \\ \\ 10x-9x=-12-5 \\ \\ x=-17 \end{gathered}`

The number is -17.
