7/1 minus what equals 2/1?

Here we will show you how to calculate "what" in this sentence: "7/1 minus what equals 2/1?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

7/1 - x = 2/1

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 7/1 on both sides like this:

7/1 - 7/1 - x = 2/1 - 7/1

7/1 - 7/1 - x leaves -x and 2/1 - 7/1 is -5 which means we end up with -x = -5. Then, you multiply each side by -1 to get x = 5. Therefore, the answer to "7/1 minus what equals 2/1?" is as follows:

5

It is always good to double-check your math to make sure you did it right. When we entered 5 for x in this equation 7/1 - x = 2/1, we get the following true equation which means our math is correct.

7/1 - 5 = 2/1
