To find the answer to "What two numbers have a product of 93 and a sum of 67?" we first state what we know. We are looking for x and y and we know that x • y = 93 and x + y = 67.
Before we keep going, it is important to know that x • y is the same as y • x and x + y is the same as y + x. The two variables are interchangeable. Which means that when we create one equation to solve the problem, we will have two answers.
To solve the problem, we take x + y = 67 and solve it for y to get y = 67 - x. Then, we replace y in x • y = 93 with 67 - x to get this:
x • (67 - x) = 93
Like we said above, the x and y are interchangeable, therefore the x in the equation above could also be y. The bottom line is that when we solved the equation we got two answers which are the two numbers that have a product of 93 and a sum of 67. The numbers are:
1.41807
65.58193
That's it! The two numbers that have a product of 93 and a sum of 67 are 1.41807 and 65.58193 as proven below:
1.41807 • 65.58193 ≈ 93
1.41807 + 65.58193 = 67
Note: Answers are rounded up to the nearest five decimals if necessary so the answers may not be exact.
