Algebra.Com's Answer #277419 by richard1234(7193)![]() ![]() You can put this solution on YOUR website! I'm pretty sure you can easily solve both systems by adding the two equations together (besides, the problem tells you how to solve it). However, you'll have to multiply one of the equations on the second problem by -1, so that you can add and the y's will cancel out. \n" ); document.write( " |
