5t + 3b = 34.75 & 3t + b = 17.25, first you need to solve for be by subtracting 3t from 17.25

anonymous · Answer

Once you have b, you input that into the other equation and find that 5t +3 "b" = 34.75. You can get the solution for a tube of paint. Then you are able to solve for b.

anonymous · Answer

You can solve either variable first and if you solved for t first. It would eliminate an extra step as you don't have to know how much a tube of paint costs.
