Let x=number of years that elapses until I am 3 times the age of the youngest
Then 58+x=my age at that time
And 11+x=age of the youngest at that time
Sooooo:
58+x=3(11+x)
58+x=33+3x
58-33=2x
25=2x
x=12.5 years
58+x=58+12.5=70.5 -----my age when I am 3 time the age of the youngest
11+x=11+12.5=23.5------the youngest's age at that time
CK
3*23.5=70.5
70.5=70.5
Hope this helps
