Algebra.Com's Answer #52914 by tazoftroy(22)![]() ![]() ![]() You can put this solution on YOUR website! First, add the last two equations to eliminate both the y and the z. You get \n" ); document.write( "Then, add the first and last equation. You get \n" ); document.write( "Now, we need to eliminate the x from one other equation so plug x into the last equation to get \n" ); document.write( "Now multiply this by 2 in order to eliminate the z. \n" ); document.write( "Subtract the two to get \n" ); document.write( "Now just plug x and y in one of the equations to get |
