Question

The sum of three times a number and six is twelve.

Answer 1

For this case we must raise the equation according to the given statement.

Let the variable "x" be the unknown number.

So, three times the number is:
`3x`

If to that term is added "6" we have:

`3x+6`

The sum of both terms is "12", then:

`3x+6 = 12`

Thus, the equation is:
`3x+6 = 12`

Answer:

`3x+6 = 12`
