Answer:

13

Step-by-step explanation:

45 - 6 = 39/3 = 13

Answer:

Forty-five is six more than three times 13.

Step-by-step explanation:

First, you have to set up the equation. We know 45 equals three times a number, 3x, plus 6.

45 = 3x + 6

Subtract 6 from both sides.

39 = 3x

Divide by 3 to isolate the x, and you get 13. Hope that helps!
