1. Make the equation. The product of the number and 6 equals the sum of the number and 45, so the equation would be 6x = x + 45.
2. Subtract x from both sides. You'll get 6x - x = 45.
3. You can combine like-terms by subtracting 6x - x. This is the same as 6x - 1x, which is 5x. You'll get 5x = 45.
4. Divide both sides by 5 to get x = 9.
Therefore, the number is 9.
