You can put this solution on YOUR website! One number is 11 more than twice another number. If the sum of the numbers is twice their difference, find the numbers
-----
Equations:
x = 2y + 11
x+y = 2(x-y)
-------------
Simplify the 2nd equation:
x+y = 2x-2y
x = 3y
---
Substitute that into the 1st equation:
3y = 2y+11
y = 11
----
Solve for "x":
x = 3y
x = 3*11
x = 33
