One number is two more than twice another, their product is 60. Determine both numbers
-------------
Equations:
x = 2y + 2
--
xy = 60
-----
Substitute for "x" and solve for "y"::
(2y+2)y = 60
2(y+1)y = 60
y^2+y = 30
y^2+y-30 = 0
Factor::
(y+6)(y-5) = 0
Positive solution::
y = 5
-----
Since xy = 60 m x = 60/5 = 12
