Question 196107
Let {{{x}}} = Lee's age now
Then {{{x - 7}}}= Phil's age now
{{{x - 11}}}= Lee's age {{{11}}} years ago
{{{x - 7 - 11}}}= Phil's age {{{11}}} years ago
{{{x - 11 = 2*(x - 7 - 11)}}}
{{{x - 11 = 2x - 14 - 22}}}
{{{-11 = x - 36}}}
{{{36 - 11 = x}}}
{{{x = 25}}}
{{{x - 7 = 18}}}
Lee's age now is 25 and Phil's age now is 18
check answer:
{{{x - 11 = 2*(x - 7 - 11)}}}
{{{25 - 11 = 2*(18 - 11)}}}
{{{14 = 2*7}}}
{{{14 = 14}}}
OK
