You can put this solution on YOUR website!
Are you allowed to use graphing calculators? In particular, if you are allowed to use a TI 85 or 86, there is a function on your calculator called [2nd] [SIMULT] that solves systems of equations without having to use either the elimination method or Cramer's Rule. If you have a TI 83+ or a TI 84, look in [APPS] for a program called [POLYSMLT]. If you don't have this program on these calculators, you can get it from Texas Instruments and have it put on your calculator. It's the easy way to solve a problem if it is allowed and if you have a calculator that will do it.\r
