xy = 6
x + y = 8 so y = 8 - x
xy = 6 substitute y with 8 - x
x(8 - x) = 6
8x - x2 = 6 subtract 6 to both sides, then multiply each term by -1
x2 - 8x + 6 = 0 use the quadratic formula to find x
x = (8 ± √(64 - 24)/2
x = (8 ± √40)/2 write 2 as 4 into the radical
x = 8/2 ± √(40/4)
x = 4 + √10 or x = 4 - √10
Therefore, the numbers are 4 + √10 and 4 - √10.

6 and 8 do.

It is: 6 because (6*7)+8 = 50

you cannot add a and 8. you can multiply them to get 8a. but a variable and number cannot add
6 and 2
The easiest way is to multiply the original number by 1.08. Otherwise, multiply the original number by .08 and add the resulting number to the original number.
8- 6 multiplied by 8 is 48
