Answer: n=20
Step-by-step explanation:
-4n=-80
Since -4 is being multiplied with n, you divide by -4 to get n by itself. Then you divide -80 by -4 to balance the equation out.
-4n/-4=-80/-4
n=20
You check your answer by pluging 20 in for n in the original equation.
-4(20)=-80
The final answer is n=20
