What plus 5/8 equals 3/7?

Here we will show you how to calculate "what" in this sentence: "What plus 5/8 equals 3/7?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

x + 5/8 = 3/7

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 5/8 on both sides like this:

x + 5/8 - 5/8 = 3/7 - 5/8

x + 5/8 - 5/8 leaves x and 3/7 - 5/8 is -11/56 which means we end up with x = -11/56. Therefore, the answer to "What plus 5/8 equals 3/7?" is as follows:

-11/56

It is always good to double-check your math to make sure you did it right. When we entered -11/56 for x in this equation x + 5/8 = 3/7, we get the following true equation which means our math is correct.
