Answer:
6 • 7 = 42
6 + 7 = 13
Answer is: 6 & 7
Step-by-step explanation:
To find the answer to "What two numbers have a product of 42 and a sum of 13?" we first state what we know. We are looking for x and y and we know that x • y = 42 and x + y = 13.
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 = 13 and solve it for y to get y = 13 - x. Then, we replace y in x • y = 42 with 13 - x to get this:
x • (13 - x) = 42
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 42 and a sum of 13. The numbers are:
6
