Question

I am thinking of a number if I divided by 10 then add 6 I get nine what is my number

Answer 1

Let the number be y;

From the question, we can derive the below eaquation;

`(y)/(10)+6=9`

Let's go ahead and solve for y;

`\begin{gathered} (y)/(10)=9-6 \\ y=10\ast3 \\ y=30 \end{gathered}`

So, the number is 30.
