In other words, if <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=2x-7%3C=0 ALIGN=MIDDLE  ALT=\"2x-7%3C=0\"   DISABLED_style= \"max-width:90%; height:auto;\" >, then the log isn't defined. Solve for 'x' to get <IMG STYLE=\"max-width:80%;\" SRC=/cgi-bin/plot-formula.mpl?expression=x%3C=7%2F2 ALIGN=MIDDLE  ALT=\"x%3C=7%2F2\"   DISABLED_style= \"max-width:90%; height:auto;\" >.
