Question 700131
Let {{{ x }}} = Richard's age now
{{{ x + 3 }}} = His age in 3 years
{{{ x - 19 }}} = His age 19 years ago
given:
{{{ x + 3 = 2*( x - 19 ) }}}
{{{ x + 3 = 2x - 38 }}}
{{{ x = 41 }}}
Richard is 41 now
check:
{{{ x + 3 = 2*( x - 19 ) }}}
{{{ 41 + 3 = 2*( 41 - 19 ) }}}
{{{ 44 = 2*22 }}}
{{{ 44 = 44 }}}
