This is equivalent to solving the simultaneous equation set {x, y: x + y = 7, xy = 3}.
By rearranging and substituting, we find that x = 7 - y, and that (7 - y)y = 3.
We can expand and simply to gain -y2 + 7y - 3 = 0, a relatively simple equation called a quadratic, and one which has a precise formula for its solution.
Using this formula, we find that y = 0.459 and y = 6.541. Note that because these add to 7, we will end up with the same answers for x, i.e. for y = 0.459, x = 6.541 and vice versa.
Regardless of the way you choose to then label the numbers, the solution is (0.459, 6.541). These add to 7 and multiply to 3.

What does associative properties of multiplication mean?
The associative property of multiplication states that for any three numbers a, b and c, (a * b) * c = a * (b * c) and so we can write either as a * b * c without ambiguity. ie, when multiplying three numbers together, you can multiply the first two together and then multiply the result of that by the third, or multiply the second two numbers together and multiply that result by the first, and you will get the same answer.
