8/7 minus what equals 9/3?

Here we will show you how to calculate "what" in this sentence: "8/7 minus what equals 9/3?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

8/7 - x = 9/3

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 8/7 on both sides like this:

8/7 - 8/7 - x = 9/3 - 8/7

8/7 - 8/7 - x leaves -x and 9/3 - 8/7 is 1 6/7 which means we end up with -x = 1 6/7. Then, you multiply each side by -1 to get x = -1 6/7. Therefore, the answer to "8/7 minus what equals 9/3?" is as follows:

-1 6/7

It is always good to double-check your math to make sure you did it right. When we entered -1 6/7 for x in this equation 8/7 - x = 9/3, we get the following true equation which means our math is correct.
