You can put this solution on YOUR website! One number is seven less than five times another. If their sum is increased by six, the result is twenty-three. Find the numbers.
--------------------------------
Equations::
x = 5y-7
x+y + 6 = 23
-----------
Substitute for "x" and solve for "y":
5y-7 + y + 6 = 23
----
6y -1 = 23
6y = 24
y = 4
----
Solve for "x":
x = 5y-7
x = 5*4-7
x = 13
