Answer:

Step-by-step explanation:

Isolate n on one side of the equation.
First, subtract 12 from both sides.
4n+12-12=4-12
Solve.
4-12=-8
4n=-8
Then, divide by 4 from both sides.
4n/4=-8/4
Solve.
Divide the numbers from left to right.
-8/4=-2
n=-2

So, the final answer is n=-2.
Let's use the variable (x) in this situation. 7 times x equals 1, or 7x = 1
first, find the opposite of 7x. We want to get x by itself. To find the opposite of 7x you would divide 7x by 7, and then do the same thing to the other side.
x = .14
.14 as a fraction would be 14/100
