Michael’s father is 42 years old. Michael’s age is represented by w. If you multiply Michael’s age by 4 and - 10 you get his dad’s age. Write an equation for to solve

there is only one way to arrange all the eight relative to each other because they are not distinct. we have

now there are nine places to place an (and not more than one in one place).   because we have four symbols, we need to choose four of these nine places to insert an . order does not matter because the are not distinct.

thus there are 1 · c(9,4) ways, or, if we calculate it,

thus there are 126 ways to form such "words."

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
