4/1 minus what equals 5/1?

Here we will show you how to calculate "what" in this sentence: "4/1 minus what equals 5/1?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

4/1 - x = 5/1

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 4/1 on both sides like this:

4/1 - 4/1 - x = 5/1 - 4/1

4/1 - 4/1 - x leaves -x and 5/1 - 4/1 is 1 which means we end up with -x = 1. Then, you multiply each side by -1 to get x = -1. Therefore, the answer to "4/1 minus what equals 5/1?" is as follows:

-1

It is always good to double-check your math to make sure you did it right. When we entered -1 for x in this equation 4/1 - x = 5/1, we get the following true equation which means our math is correct.

4/1 - -1 = 5/1
