You can put this solution on YOUR website! the sum of three integers is 124.the third is seven more than the second and the second is six times the first.Find the integers.
--------------------------
x + y + z = 124
z = y + 7
y = 6x
===============
Substitute for x and for z and solve for "z"::
(y/6) + y + y+7 = 124
------------------------
(y/6) + 2y = 117
-------
(13/6)y = 117
---------
y = (6/13)117
y = 144
----
x = 144/6 = 24
----
z = y + 7 = 151
