Ang and Meryl have a total of 2 model airplanes in their collection. Meryl has 6 moreplanes than Ang. Which equation could be solved to find a, the number of planes Ang has?
a+6=24, a+6a=24, a6=24, or a+a+6=24

It would help if you proofread your questions before you posted them.
If they only have "2 model airplanes" how can one have 6 more than the other?
