Question

What is the value of n? n–2= 10n+ 4/2 Enter your answer in the box.

Answer 1

n = -1

Explanation:

You start with your problem.

n-2=10n+4/2 then you have to unlock the numerator by multiplying by 2 on each sides giving you.

2n-4=10n+4 then you move all the things in your equation to give you.

-2n-4-2n-4

-8 - 8n =

n= -1

Answer 2

-4 / 9

Explanation:

n - 2 = 10n + 4/2

n - 10n = 4/2 + 2

-9n = 4/2 + 4/2 ( taking LCM of 4/2 and 2)

-9n = 8/2

-9n = 4

n = 4 / -9

therefore n = -4 /9 ( since the minus sign doesn't make a difference whether placed at numerator or denominator) .
