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: [tex]3x[/tex]
If to that term is added "6" we have:
[tex]3x+6[/tex]
The sum of both terms is "12", then:
[tex]3x+6 = 12[/tex]
Thus, the equation is: [tex]3x+6 = 12[/tex]
Answer:
[tex]3x+6 = 12[/tex]
