Caitlyn spends $17 at the store. She buys a mop for $5 and 3 bottles of floor cleaner. If x represents the cost of each bottle of cleaner, the equation that can be used to find the value of x is 3 x + 5 = 17. Which shows the first step that should be taken to verify that $4 is the solution to the equation? 3 (4) minus 5 = 17 3 (4) = 17 + 4 3 (4) + 5 = 17 + 5 3 (4) + 5 = 17
