What is the answer 4.2m plus 3.9n-1.4m-1.5n?
There's no answer, because there's no question here.You could tidy it up a bit if you wanted to, and it would look a lot neater.4.2m + 3.9n - 1.4m - 1.5n =2.8m - 2.4n =0.4 (7m - 6n)But that's still not an answer to anything. Except maybe an elementary algebraexercise that says "Simplify" or "Tidy up this expression:".
What does it mean when it says to simplify expressions?
