Algebra.Com's Answer #638909 by FrankM(1040) You can put this solution on YOUR website! 1/2x+y=7/6\r \n" ); document.write( "\n" ); document.write( "Multiply both sides by 6 to get rid of fractions.\r \n" ); document.write( "\n" ); document.write( "3x+6y=7\r \n" ); document.write( "\n" ); document.write( "x+2y=4.5\r \n" ); document.write( "\n" ); document.write( "Multiply both sides by 2 to get rid of fractions.\r \n" ); document.write( "\n" ); document.write( "2x+4y=9\r \n" ); document.write( "\n" ); document.write( "Notice that the coefficients of the second equations x and y are both 2/3 the first equation. If you multiply by 1.5 you get\r \n" ); document.write( "\n" ); document.write( "3x+6y=13.5\r \n" ); document.write( "\n" ); document.write( "But, first equation is \r \n" ); document.write( "\n" ); document.write( "3x+6y=7\r \n" ); document.write( "\n" ); document.write( "These 2 lines are parallel.
