You can put this solution on YOUR website! The problem is easy.
The only solution to is --> -->
Substituting into you get ,
which has two solutions: and
The solutions to the system are the two pairs (0,5) and (0,-5), or and
NOTE:
If the problem had been , the system could be solved similarly, with a little more work.
The answer is not pretty, so that was not the intended problem.
(Classroom problems are supposed to have pretty answers).
In that case, solving for X to substitute in the other equation we get --> --> to substitute.
So you have --> -->
At this point, I would multiply both sides to the equal sign times 9 to get rid of fractions. I would get -->
That equation yields two ugly solutions for Y:
Each ugly Y can be substituted into to get the corresponding ugly X values
for a pair of ugly solutions.
