**PLS HELP DUE SOON** Here is a balanced hanger diagram in which a circle has a mass of 3 grams and a square has a mass of 2 grams. Which equations could represent the diagram, assuming t represents the triangles?

3c + 2s + 2t = 3c + 2s + 5t

2t + 21 = 5t + 12

3(3) + 6(2) + 2t = 2(3) + 3(2) + 5t

2t + 9 = 5t + 5

5t + 6 + 6 = 9 + 12 + 2t
