<h3>Simplifying an expression</h3>
From the question, we are to determine the expression for the total number of services
From the given information,
Number of types of massages = 4x + 3
Number of types of manicures = -6x + 5
Number of types of pedicures = 8x - 7
Then,
Total number of services = 4x + 3 + (-6x + 5) + 8x - 7
Total number of services = 4x + 3 - 6x + 5 + 8x - 7
Total number of services = 4x - 6x + 8x - 7 + 3 + 5
Total number of services = 6x - 1
Hence, the expression for the total number of services the have to choose from is 6x - 1
