If the sum of two numbers is 42 one number plus two then times the other number is 57 what are the two numbers?
Msalaz10
If X+Y = 42, and 2X + Y = 57, then if you subtract the first equation from the second,
2X + 1Y = 57
1X + 1Y = 42 -
----------------
1X + 0Y = 15
That means that Y = 27.
15 + 27 = 42
15 + 15 + 27 = 57.
