Question 887677
w for woman's age
d for daughter's age


Two Years Ago:  {{{w-2=7(d-2)}}}
{{{w-2=7d-14}}}
{{{w-7d=2-14}}}
{{{w-7d=-12}}}
{{{highlight(7d-w=12)}}}


In Three Years:  {{{w+3=4(d+3)}}}
{{{w+3=4d+12}}}
{{{w=4d+9}}}
{{{highlight(w-4d=9)}}}


Two equations in d and w.  Solve both for w and equate the expressions, and solve for the value
of d.  Find w from the now found d.
