Question 182669
</pre><font size=4><b>
Let Sue's age={{{x}}}
Then, Leah's age={{{highlight(6)+x}}}, 6 yrs older than Sue
Also, John' age={{{highlight(5)+6+x}}}, 5 yrs older than Leah

Therefore:
{{{Sue+Leah+John=41}}}
{{{x+6+x+5+6+x=41}}}
{{{3x+17=41}}}
{{{3x=41-17=24}}}------->{{{cross(3)x/cross(3)=cross(24)8/cross(3)}}}
{{{highlight(x=8yrs)}}}, Sue's Age
Leah's age={{{6+8=14yrs}}}
John's Age={{{5+14=19yrs}}}
Let's Check:
{{{8+14+19=41}}}
{{{41yrs=41yrs}}}
thank you,
