Question #299fa

Answer 1

`2(9-x)+(9-x)=9`

Explanation:

We have to write an equation such that

9 equal to some expression. On solving the

equation we get the other number.

The other number is `x`

As per the statment `2xx(9-x)` is the other number

The difference is `9-x`

The value of the other number plus the difference between the two numbers is equal to `9`

Then the equation is -

`2xx(9-x)+(9-x)=9`

Let us verify it -

`18-2x+9-x=9`
`27-3x=9`
`-3x=9-27=-18`
`x=(-18)/(-3)=6`
`x=6`
