\r
\n" ); document.write( "\n" ); document.write( "(r + 6)/5 = ( r + 8 ) /7 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " now multiply both sides of the equation by the lowest common multiple of 5 and 7\r
\n" ); document.write( "\n" ); document.write( "that is,
\n" ); document.write( "35 * (r + 6)/5 = 35 * ( r + 8 )/7\r
\n" ); document.write( "\n" ); document.write( "7 * (r + 6 ) = 5* (r+8)\r
\n" ); document.write( "\n" ); document.write( "now remove the brackets by multiplying the terms out side the brackets.\r
\n" ); document.write( "\n" ); document.write( "7 * r + 7 * 6 = 5 * r + 5* 8\r
\n" ); document.write( "\n" ); document.write( "7r + 42 = 5r + 40
\n" ); document.write( "
\n" ); document.write( "now bring the like terms together.\r
\n" ); document.write( "\n" ); document.write( "7r - 5r = 40 - 42\r
\n" ); document.write( "\n" ); document.write( "==> 2r = -2\r
\n" ); document.write( "\n" ); document.write( "now divide both sides of the equation by 2\r
\n" ); document.write( "\n" ); document.write( "==> r = -2/2\r
\n" ); document.write( "\n" ); document.write( "==> r = -1\r
\n" ); document.write( "
