To form a subtraction equation using the numbers provided, let's analyze the numbers:
The equation format is: \[ \text{number} - 14 = \text{result} \]
From the numbers provided (15, 1, 12, 14, 4, 11), we need to find a number greater than 14 so that we end up with a non-negative result after subtraction. The only numbers we can use that fulfill this condition are 15 and 12.
- Using 15: \[ 15 - 14 = 1 \]
So the complete equation is: \[ 15 - 14 = 1 \]
- Using 12: \[ 12 - 14 \] This does not give a valid result since it would be negative.
Thus, the only valid subtraction equation is: \[ 15 - 14 = 1 \]
The answers in numerals are: 15 and 1.
