Question 665518
Let {{{ x }}} = the length of the shorter piece
{{{ 22 - x }}} = the length of the longer piece
given:
{{{ 2x = 22 - x - 4 }}}
{{{ 2x + x = 22 - 4 }}}
{{{ 3x = 18 }}}
{{{ x = 6 }}}
{{{ 22 - x = 22 - 6 }}}
{{{ 22 - 6 = 16 }}}
The pieces are 6 ft and 16 ft
check:
Twice the shorter piece is 2 x 6 = 12
The longer piece is 4' longer, or 16'
OK
