Question 32256
1. {{{ p+2 = s }}}
2. {{{ (p+4) + (s+4) = 36 }}}
Substitute equation 1 into equation 2
{{{ (p+4) + ((p+2)+4) = 36 }}}
combine like terms
{{{ 2p + 10 = 36 }}}
subtract 10
{{{ 2p = 26 }}}
divide by 2
{{{ p = 13 }}}
Plug this back into the first equation
{{{ p+2 = s }}}
{{{ 13+2 = s }}}
{{{ 15 = s }}}

CHECK:
{{{ (p+4) + (s+4) = 36 }}}
{{{ (13+4) + (15+4)= 36 }}}
{{{ 17 + 19 = 36 }}}
{{{ 36 = 36 }}}
YES!!!
