Zane has twice the number of pieces of bubble gum as Cody. Together, the boys have 42 pieces.
How many pieces of gum does Zane have?

28

Step-by-step explanation: 2x+x=42 (equation i used to solve for Cody)

2x+x=42 (add the similar elements)

3x=42

(divide both sides by 3)

x=14 (cody)

Zane has twice the amount so double 14 to get 28
