Michael had three π‘₯ plus six coins and gave two π‘₯ plus three coins to James. How many coins does Michael have left?

In order to solve this problem, we need to subtract two π‘₯ plus three from three π‘₯ plus six. We can do this by grouping or collecting the like terms: three π‘₯ minus two π‘₯ and six minus three. Three π‘₯ minus two π‘₯ is equal to π‘₯ and six minus three is equal to three.

This means that after Michael gave two π‘₯ plus three coins to James, he has π‘₯ plus three coins left.
