Remove the decimals in the first equation by multiplying
all the terms by 10
becomes:
which becomes:
Since the second one has a fraction, change the decimals
0.5 to
becomes:
Now multiply through by LCD = 46
, which becomes:
Now the system is:
To eliminate the y-terms, multiply the first
equation through by 23 and the second equation through by 2
Add the two equations together term by term and
you see the y-terms's cancel out:
------------
The fraction will reduce by dividing top and bottom by 5
----------------
Since x is such an ugly looking fraction, do not
substitute it into one of the equations as you
normally do when the solution to the first variable
is a whole number.
Instead, go back to this sytem and eliminate the x-terms:
To eliminate the x-terms do, multiply the first equation
through by 23 and the second equation through by -3
Add the two equations together term by term and
you see the x-terms's cancel out:
------------
The fraction will reduce by dividing top and bottom by 5
--------------
So the solution is an ordered pair of ugly looking fractions:
(x,y) = (, )
