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:

$3x+6 = 12$
