Question 449945
You can make the table, but here is how I
would solve it:
How many times Lisa's age is Marcus now?
{{{ 49/15 = 3.27 }}}
Let {{{x}}} = number of years I want to add to both ages
so that  {{{ 49 + x = 3*( 15 + x ) }}}
{{{ 49 + x = 45 + 3x }}}
{{{ 2x = 49 - 45 }}}
{{{ 2x = 4 }}}
{{{ x = 2 }}}
In 2 years, Marcus will be 3 times Lisa's age
check:
{{{ 49 + 2 = 51 }}}
{{{ 15 + 2 = 17 }}}
{{{ 51/17 = 3 }}}
OK
For a table, you can list x, 49 + x, 15 + x, 3*(15 + x)
and x=1, x=2, x=3
