Question 1044293
Let {{{ x }}} = miles that Pedro walked
-------------------
I guess the 1st sentence means that you add the
miles each walked and the total is {{{ 17 }}}
-------------------
The miles that Julio walked is:
{{{ 2x - 1 }}}
-------------------
{{{ x + 2x - 1 = 17 }}}
{{{ 3x = 18 }}}
{{{ x = 6 }}}
and
{{{ 2x - 1 = 2*6 - 1 }}}
{{{ 2x - 1 = 11 }}}
--------------------
Pedro walked 6 miles
Julio walked 11 miles
