Algebra.Com's Answer #461826 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! Hint: Multiply both sides of equation 1 by -3 to get -15x-6y = -24\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Then add this to equation 2\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "-15x-6y = -24 \n" ); document.write( "12x + 6y = 20 \n" ); document.write( "-------------- \n" ); document.write( "-3x + 0y = -4\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "so -3x = -4\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "solve for x, then use this to find y. \n" ); document.write( " |
