The question is an illustration of equivalent equations.
<em>There are 11 units in all</em>
The given parameters are:
<u>Sage</u>
<u>Tristan</u>
Andre has twice of what Sage has
So, the total unit is:
<em>Sage has 2 units</em>
<em>Tristan has 5 units</em>
<em />
Because, Andre has twice of what <em>Sage has,</em>
Andre's number of units would be 4
So, we have:
Hence, there are 11 units in all
