You can put this solution on YOUR website! What you have is 2 linear equations.
That means that you've got a
and an and not a and
an or
-------------------------
A linear equation just means that the plot
is a straight line. Two equations are called
a system, and teh solution will be a
point ( x,y ) that satisfies both equations
-----------------------------------
-----------------
Multiply both sides of (1) by and
subtract (1) from (2)
Now plug this result back into either
equation to find
-------------
So, the solution is ( -7 ,-16 )
Here a plot of both lines showing the
intersection at ( -7, -16 )
