Question

- If you divide a number by four and then add six, you
get eighteen. What is the number?

Answer 1

48

Explanation:

let's say x is our number

if we divide it by 4 we get

`x\rightarrow(x)/(4)`

if we add 6 we get

`x\rightarrow(x)/(4) \rightarrow(x)/(4)+6`

and that equals 18 so

`(x)/(4)+6=18\\\\(x)/(4)+6-6=18-6\\\\(x)/(4)+0=12\\\\(x)/(4)=12\\\\4((x)/(4))=4(12)\\\\x=48`

so our number is 48

Answer 2

48

Explanation:

Create an equation to represent this, where x is the unknown number.

`(x)/(4)` + 6 = 18

Solve for x, by first subtracting 6 from both sides:

`(x)/(4)` = 12

Multiply each side by 4:

x = 48

So, the number is 48
