Question 778550
the difference between two numbers is 13.Twice the smaller plus three times the larger is 129.What are the numbers?
--------
Equations:
x - y = 13
2x + 3y = 129
---------
Modify for elimination:
2x - 2y = 26
2x + 3y = 129
-----
Subtract and solve for "y":
5y = 103
y = 103/5
----
Solve for "x":
x - (103/5) = (65/5)
x = 168/5
