x+y=-3
xy=-42
Isolate y in both equations:
y=x-3
y=-42/x
x-3=-42/x
x^2-3x=-42
x^2-3x+42=0
x=(3±√-157)/2
x is imaginary

This is mathematically impossible. The highest product that you can get with two numbers that make thirteen is 42 (7*6). The lowest sum you can get for two numbers with a product of 155 is 36 (31 and 5). All in all, it's impossible.

six, seven 7 + 6 = 13 (sum) 7 - 6 = 1 (difference) 7 x 6 = 42 (product)
the two numbers are 50.54657341 and -8.546573405 That was a good try. The two numbers do add up to 42, but unfortunately the product of a positive and a negative is negative, so that they multiply to give -432 rather than 432. The correct answer is 18 and 24
