5/1 minus what equals 3/1?

Here we will show you how to calculate "what" in this sentence: "5/1 minus what equals 3/1?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

5/1 - x = 3/1

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 5/1 on both sides like this:

5/1 - 5/1 - x = 3/1 - 5/1

5/1 - 5/1 - x leaves -x and 3/1 - 5/1 is -2 which means we end up with -x = -2. Then, you multiply each side by -1 to get x = 2. Therefore, the answer to "5/1 minus what equals 3/1?" is as follows:

2

It is always good to double-check your math to make sure you did it right. When we entered 2 for x in this equation 5/1 - x = 3/1, we get the following true equation which means our math is correct.
