Let x = big number
Let y = small number
x + y = 4y
y - 2x = 30

the sum of two numbers is the same as four times the smaller number. if twice the larger is decresed by the smaller the result 30. find the numbers?
----------------------
Let x = larger number
Let y = smaller number
x + y = 4y --> x = 3y
2x - y = 30
-----------
2*3y - y = 30
5y = 30
y = 6
x = 18
