Question

please simplify this n - 10 + 9n - 3

Answer 1

Answer:

10n - 13

Step-by-step explanation:

All you have to do is combine the numbers/variables alike.

n + 9n (It's addition because the 9 is positive) = 10n

-10 - 3 (It's a negative minus 3 because it's subtraction 10 and 3) = -13

Now you just have to combine the two (The variable(s) ALWAYS go first, generally in alphabetical order)

10n - 13

And there's your answer!
