Question

-5n - 3(1+2n) = -25

Answer 1

Explanation:

-5n-3(1+2n)= -25

-5n-3-6n= -25 Distributive property (-3*1) and (-3*2n)

-11n-3= -25 -5n-6n = -11n

+3 +3 Add 3 to both sides to leave n alone

-11n= -25

----- ----- Divide by -11 on both sides to get n alone.

-11 -11

n= -2.2727272....

You should round however instructions are given.
