Question 1167095
------------------------------------------------------
Maggie's age is 25 years than three times Karen's age.
------------------------------------------------------


Missing a word.  Need to say EITHER "more than" or "less than".  



If this solution does not give what you want, then you figure out what needs to change:


--------
--------
Maggie, Amy, and Karen are relatives. They have lived a total of 105 years combined. Maggie's age is 25 years than three times Karen's age. Amy's age is twice the sum of Maggie and Karen's ages.
--------
--------


{{{system(m+a+k=105,m=3k-25,a=2(m+k))}}}

Notice substitutions for m and a can be made and have an equation in just variable k.


{{{(3k-25)+2(m+k)+k=105}}}
and then
{{{(3k-25)+2((3k-25)+k)+k=105}}}
and simplifying
{{{3k-25+2(4k-25)+k=105}}}
{{{3k-25+8k-50+k=105}}}
{{{12k-75=105}}}
{{{12k=180}}}
{{{highlight(k=15)}}}
-


RESULTS
{{{highlight(Maggie=45-25=highlight_green(20))}}}
{{{highlight(Amy=70)}}}
{{{highlight(Karen=15)}}}
