Question 878561
Present:  {{{b=5r}}}

Six Years Future:  {{{r+6=(3/7)(b+6)}}}


Solve:  {{{7(r+6)=3(b+6)}}}
{{{7r+42=3b+18}}}
{{{7r-3b=18-42}}}
{{{7r-3b=-14}}}
{{{3b-7r=14}}}
Substitute.
{{{3*5r-7r=14}}}
{{{8r=14}}}
{{{r=14/8}}}, not a whole number for Ricky.
{{{r=7/4}}}.
-
{{{b=5(7/4)}}}
{{{b=35/4}}}, also not a whole number.


Brittany's age present plus y years, will be 60 years.
What is y?
{{{35/4+y=60}}}
{{{y=60-35/4}}}
{{{y=240/4-35/4}}}
{{{y=205/4}}}
-
What will be Ricky's age at that time?
{{{r+205/4=7/4+205/4}}}
{{{212/4=53}}}
<b>Ricky to be 53 years old when Brittany is 60 years old.</b>
