Question

Expand the expression and combine like terms: −4(−11+4n)−3(−2n+9)

Answer 1

Easy,

-4(-11+4n)-3(-2n+9)

Take them apart and multiply them out...

-4(-11+4n)= 44-16n
and
-3(-2n+9)= 6n-27

Now add the apples and oranges..

44-16n+6n-27

44-27=17

-16n+6n=-10n

Thus, your answer is, -10n+17.

Answer 2

−4(−11+4n)−3(−2n+9)

44 - 16n + 6n - 27

17 - 10n = 0

17 = 10n

n = $\frac{17}{10}$
