All triangles have the same value, and all circles have the same value. What is the sum of two circles?

 

\(\circ + \circ + \Delta = 15\)
\(\circ + \Delta + \Delta = 23\)

2x + y =  15    ⇒    y  =   15 -  2x       (1)

x + 2y  =  23           (2)

 

Sub   (1)  into (2)

x  + 2 ( 15 - 2x)  = 23

-3x + 30   =23

-3x  =  -7

x = 7/3    = the   value of one circle

 

So  2 circles  =  14/3
