At an arcade, tokens are placed in a bin and the mass is measured. The bin has a mass of 360 grams when it is empty. Each token has a mass of 6 grams. The bin full of tokens has a mass of 1,680 grams. Write an equation to find t, the number of tokens in the bin.

Back

6t = 1680 - 360

Front

Solve the equation: t + 26 - 7 = 39

Back

t = 20
