 07-29-2007 #3 myfateismydestiny Guest   Posts: n/a Here is the problem-(3p-1)+12>-2(p+4)-12First,we've to work out those in the bracket.But they can't be simplified furthermoreThe equation is equivalent to-3p+1+12>-2p-8-12=-2p+13>-2p-20Bringing the constants on one side & the variables on another,=-2p+2p>-20-13=0>-33This implies that the statement(problem) is TRUE.
