Question

-2 ( 6 + 7n ) = 3n + 5

Answer 1

n = -1

Step-by-step explanation:

First we need to distribute the -2 throughout the variable getting us to

-12 - 14n = 3n + 5

Then we need to move the variable n to one side and isolate it. To do this, subtract 3n from both sides and add 12 to both sides.

-17n = 17

Now, we need to remove the co-efficient from n, so we need to divide both side by -17.

n = -1
