You can put this solution on YOUR website!
s + p + c = 40
\n" ); document.write( "c = 4p
\n" ); document.write( "s = p - 2\r
\n" ); document.write( "\n" ); document.write( "---------------
\n" ); document.write( "The objective is to get an equation that has only one variable.
\n" ); document.write( "You are told c=4p
\n" ); document.write( "You are told s=p-2
\n" ); document.write( "Substitute that information into the 1st equation to get:
\n" ); document.write( "(p-2) +p +4p = 40
\n" ); document.write( "6p-2=40
\n" ); document.write( "6p=42
\n" ); document.write( "p=7
\n" ); document.write( "----------
\n" ); document.write( "Then c=4p=4*7=28
\n" ); document.write( "And s=p-2=7-2=5
\n" ); document.write( "---------
\n" ); document.write( "Solution:
\n" ); document.write( "p=7; s=5, c=28\r
\n" ); document.write( "\n" ); document.write( "==============
\n" ); document.write( "Cheers,
