Write an equation that represents the following problem. Susan is buying three different colors of tiles for her kitchen floor. She is buying 107 red tiles, and three times
as many navy blue tiles as beige tiles. If Susan buys 435 tiles altogether, how many tiles of each color does
she buy?
Let b equal the number of beige tiles. Your equation should start with "435 =" and use b as the only variable.
You do not have to solve the equation.
