Spencer needs 2 gallons of paint to create a mural. He has gallon of yellow paint and į gallon of blue paint.
Drag amounts of paint Spencer can add to the paint he already has to make exactly 2
gallons of paint

I don't exactly know how to answer this, maybe I need more information. But if not, then all he can do is add one gallon of yellow paint and one gallon of blue paint. If that's all the paint he has, that is all he can add. Is there a diagram that's supposed to go with this? If not, hope I answered your quesiton.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.
