Algebra.Com's Answer #138729 by alaccalac(13)![]() ![]() ![]() You can put this solution on YOUR website! Hi so say..get y alone on the top \n" ); document.write( "y=-1x+5 \n" ); document.write( "so plug it in to the bottom equation \n" ); document.write( "3x--1x+-5 \n" ); document.write( "4x=8 \n" ); document.write( "x=2 \n" ); document.write( "y=3 \n" ); document.write( "(2,3) \n" ); document.write( "Hope that clears it up! \n" ); document.write( " |
