You can put this solution on YOUR website! The sum of two numbers is 78. If three times the small number is subtracted from the larger number, the result is 14. Find the two numbers.
X+Y=78 , Equation 1
X-3Y=14 , Equation 2
Equation 1-Equation 2
(X+Y=78) - (X-3Y=14)
X+Y)-(X-3Y) = 78)-(14)
X+Y-X+3Y = 78-14
4Y = 64
Y= 16
X+Y=78
78-Y=X
78-16=X
X=62
X=62 Y=16
