\r\n" );
document.write( "-3 ≤ 1-5x ≤ 7\r\n" );
document.write( "\r\n" );
document.write( "We solve for x in the middle:\r\n" );
document.write( "\r\n" );
document.write( "Add -1 to all three sides like this:\r\n" );
document.write( "(Or you may say \"Subtract 1 from them\"):\r\n" );
document.write( "\r\n" );
document.write( "-3 ≤ 1-5x ≤ 7\r\n" );
document.write( "-1  -1     -1\r\n" );
document.write( "-------------\r\n" );
document.write( "-4 ≤  -5x ≤ 6 \r\n" );
document.write( "\r\n" );
document.write( "Now that you have \r\n" );
document.write( "\r\n" );
document.write( "-4 ≤ -5x ≤ 6\r\n" );
document.write( "\r\n" );
document.write( "Divide all three sides by -5.\r\n" );
document.write( "However when we divide an inequality by\r\n" );
document.write( "any negative number we always must reverse\r\n" );
document.write( "the direction of the inequalities, so we get\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "or\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Sometimes people prefer to leave answers with \r\n" );
document.write( "instead of , because they like to think left\r\n" );
document.write( "to right on the number line,  So we might better write \r\n" );
document.write( "that as:\r\n" );
