Algebra.Com's Answer #74131 by brianuh(2)![]() ![]() ![]() You can put this solution on YOUR website! 5x - 2y= -5\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Divide everything by 2y to get Y by itself.\r \n" ); document.write( "\n" ); document.write( "so 5x divided by -2 \r \n" ); document.write( "\n" ); document.write( "y = -5/2x 5/2\r \n" ); document.write( "\n" ); document.write( "the -5 becomes postive because negative 5 divided by negative two is a positive, so positive 5 over 2.\r \n" ); document.write( "\n" ); document.write( "the answer is\r \n" ); document.write( "\n" ); document.write( "y = -5/2x + 5/2\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "8x - 4y = 16\r \n" ); document.write( "\n" ); document.write( "Divide by -4y on all sides to get y by itself.
