4/3 minus what equals 3/7?

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

4/3 - x = 3/7

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

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

4/3 - 4/3 - x leaves -x and 3/7 - 4/3 is -19/21 which means we end up with -x = -19/21. Then, you multiply each side by -1 to get x = 19/21. Therefore, the answer to "4/3 minus what equals 3/7?" is as follows:

19/21

It is always good to double-check your math to make sure you did it right. When we entered 19/21 for x in this equation 4/3 - x = 3/7, we get the following true equation which means our math is correct.

4/3 - 19/21 = 3/7
