Question

-2(2n+4)=10 solve the equation

Answer 1

-2(2n+4) = 10
distribute the -2 through the parentheses
-4n - 8 = 10
begin to isolate n by adding 8 to each side
-4n = 18
finish isolating n by dividing both sides by -4
n = 18/-4 = -4 1/2

Answer 2

The answer is $-4 \frac{1}{2}$
First, we need to simplify the equation in parentheses
So we multiply (2n+4) by -2 which will get us -4n-8.
The equation now is $-4n-8=10$
Now we isolate the variable
Lets add the 8 to both sides of the equation
-4n-8+8=10+8
You will get -4n=18
Now divide -4n with -4 and divide 18 with -4 to "isolate the variable"
You would get n=18/-4
Simplify 18/-4 and you would get $-4 \frac{1}{2}$
N= $-4 \frac{1}{2}$
