Drew has saved three times the number of bottle caps that Liz has saved plus 2. The number of bottle caps Drew saved is also seven times the difference of the number of bottle caps and 10 that Liz has saved. Write and solve an equation to find the number of bottle caps they each have saved. Equation: L= Liz has bottle caps Drew has bottle caps 14.
