3/4 minus what equals 7/4?

Here we will show you how to calculate "what" in this sentence: "3/4 minus what equals 7/4?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

3/4 - x = 7/4

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 3/4 on both sides like this:

3/4 - 3/4 - x = 7/4 - 3/4

3/4 - 3/4 - x leaves -x and 7/4 - 3/4 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 "3/4 minus what equals 7/4?" 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 3/4 - x = 7/4, we get the following true equation which means our math is correct.

3/4 - -1 = 7/4
