Question

John has 15 more music CD's than Michael. Together they have a total of 55 CD's. How many CD's does Michael have?

Answer 1

Let's say that John has x cd's, then Michael has x - 15.


\(\Large \color{MidnightBlue}{\Rightarrow x + (x - 15) = 55 }\)
Tell me that you know how to solve for equations.

Answer 4

\(\Large \color{MidnightBlue}{\Rightarrow 2x - 15 = 55 }\)
\(\Large \color{MidnightBlue}{\Rightarrow 2x = 70 }\)
\(\Large \color{MidnightBlue}{\Rightarrow x = 35 }\)
Mike has x - 15 ----> 35 - 15 = 20
