Question 422437
There are seven less than twice the marbles in Tim’s box as there are in Amelia’s box.
t = 2a-7
-------- 
Chris has six more marbles than Amelia. 
c = a+6
--------
How many marbles does Amelia have if together the three of them have 95 marbles?
t + c + a = 95
=========================
Substitute for "t" and for "c" and solve for "a":
(2a-7)+(a+6)+a = 95
4a -1 = 95
4a = 96
a = 24 (amelia's marbles)
---
t = 2a-7 = 41 (tim's marbles)
----
c = a + 6 = 30 (chris's marbles)
====================================
