Question

A number plus itself, plus twice itself, plus 4 times itself, is equal to 104. What is the number?i need the expression and answer please

Answer 1

When the problem says "a number", it refers to a variable which we are going to call n.

So, the expression would be

`n+n+2n+4n=104`

Now, we reduce all like terms

`8n=104`

Then, we divide the equation by 8

`\begin{gathered} (8n)/(8)=(104)/(8) \\ n=13 \end{gathered}`

Therefore, the number is 13.
