D is the answer cause there is only 1 degree
To find this answer :
Step 1: Simplify both sides of the equation.
1/6x=-13
Step 2: Multiply both sides by 6.
6*(1/6x)=(6)*(-13)
You will get x=-78.
I’m guessing you want to find out (n).
That’s what I did anyway.
The answer is: n=5
Step 1: Subtract 5n from both sides.
3.2
n
+
9
−
5
n
=

n
−
1.8
n
+
9
=
0
Step 2: Subtract 9 from both sides.
−
1.8
n

9
−
9
=

Step 3: Divide both sides by -1.8.
−
