Question 1108125
35: 3☆+1❐+0△
59: 1☆+2❐+1△
50: 2☆+2❐+0△
I am assuming that the number on the left equals the variables on the right. 
I like dealing with x, y, and z
3x+y=35
2x+2y=50
-6x-2y=-70, multiplying the first by -2
-4x=-20
x=5
y=20
z=14 using these in the middle equation
2x+y+z=44, where x=star, y=square and z=triangle
