How do you solve this word problem? One number is four more than a second number. Two times the first number is 8 more than four times the second number.
----------------
Equations:
x = y + 4
2x = 4y + 8
er----
Multiply thru the 1st equation by 2
and you get:
2x = 4y + 8
----
That shows the 2nd equation is simply a multiple
of the 1st equation>
------
There are an infinite number of solutions
of the form (x,x-4) where "x" is any Real Number.
