What plus 3/7 equals 5/2?

Here we will show you how to calculate "what" in this sentence: "What plus 3/7 equals 5/2?" We start by making this word problem into an algebraic equation where "what" is the variable "x".

x + 3/7 = 5/2

To solve this equation, we want x alone on the left side of the equation so we start by subtracting 3/7 on both sides like this:

x + 3/7 - 3/7 = 5/2 - 3/7

x + 3/7 - 3/7 leaves x and 5/2 - 3/7 is 2 1/14 which means we end up with x = 2 1/14. Therefore, the answer to "What plus 3/7 equals 5/2?" is as follows:

2 1/14
