Question 804996
Is this the problem:
{{{ abs( 5 - 2a ) - 7 = 6 }}} ? If it is,
{{{ abs( 5 - 2a ) = 13 }}}
What is inside the absolute value sign can
be either {{{ 13 }}} or {{{ -13 }}}, so
{{{ 5 - 2a = 13 }}}
{{{ 2a = 5 - 13 }}}
{{{ 2a = -8 }}}
{{{ a = -4 }}}
also
{{{ 5 - 2a = -13 }}}
{{{ 2a = 18 }}}
{{{ a = 9 }}}
You can graph the 2 points
