Algebra.Com's Answer #269969 by unlockmath(1688)![]() ![]() You can put this solution on YOUR website! Hello, First let's rewrite this as: \n" ); document.write( "-36x-35y=-216 \n" ); document.write( "6x-6y=-35 \n" ); document.write( "Now we can multiply the second equation by 6 to get: \n" ); document.write( "36x-36y=-210 \n" ); document.write( "And add this to the first to get: \n" ); document.write( "-71y=-426 \n" ); document.write( "Divide -71 into both sides to get: \n" ); document.write( "y=6 \n" ); document.write( "Plug this in to find: \n" ); document.write( "x=1/6 \n" ); document.write( "Make sense? \n" ); document.write( "RJ \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
