Create and solve a linear equation that represents the model, where squares and triangles are shown evenly balanced on a balance beam. assume the weight of a square is 1 unit and the weight of a triangle is unknown.

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
