Clear out the parentheses-3p+1+12>-2p-8-12Collect like terms:-2p+13>-2p -20Add 2p to both sides:13>-20Since this statement is always true, the solution is all real numbers.

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.

p-3p+1+12> 2p+8-12so,p-2p>8-12-12-1-p>-17p>17..for this equation to be true p should be greater than 17 hope this might help...bye
