<PRE><B>Question 969777</B>
Connie is x years old
Abe is 2x
Bert is x+5 

They sum to 30

x+2x+x+5=30.

Collect terms.

4x+5=30
subtract 5 from each side
4x=25
Divide both sides by 4
x=6.25
2x=12.50
x+5=11.25

Connie is 6 1/4 years old or 6.25
Abe is 12 1/2 years old or 12.5
Bert is 11 1/4 years old or 11.25

They sum to 30.</PRE>
