You can put this solution on YOUR website! The sum of two numbers is 80 and the greatest number exceeds twice the smaller by 11. Find the numbers.
Sol'n:
let: x -the larger number
y-the smaller number
x+y=80 ---(1)
x=2y+11 ---(2)
from (2):
x-2y=11
x+y=80
=======
-3y=-69
y=23
for x:
x=80-23=57
thus: x=57 & y=23 ---answer
