Question

Simplify the expression. –5z + 4n + 18z – 10n

Answer 1

-10n+4n =-6n
-5z+18z=13z

therefore
-6n+13z is the simplified answer

Answer 2

then you simplify -6+13z

Answer 3

i dont think you can combine the -6n with the 13z. it would just be left at -6n+13z. n and z are the variables so they have to stay separate. if they were both n or both z, then you could combine.

Answer 4

its because my answers for this question are these
A.13z – 6n
B.
–23z + 14n
C.
22z + 5n
D.
–28z + 8n
