Question 335905: If one-half the smaller of number is increased by one-third the larger number, the result os 2. If one-third the snakker number increased by one-ninth the larger number, the result is 1. Find the numbers. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Let x = the smaller number
Let y = the larger number
:
Write an equation for each statement:
"If one-half the smaller of number is increased by one-third the larger number, the result is 2." x + y = 2
:
"If one-third the smaller number increased by one-ninth the larger number, the result is 1." x + y = 1
:
Multiply the 1st equation by 6, multiply the 2nd equation by 18
Subtract the 1st resulting equation from the 2nd resulting equation
6x + 2y = 18
3x + 2y = 12
----------------subtracting eliminates y, find x
3x = 6
x = 2
:
Find y using the equation 6x + 2y = 18
6(2) + 2y = 18
2y = 18 - 12
2y = 6
y = 3

:
Check solutions in the 1st original equation (2) + (3) = 2 + = 2; confirms our solutions
