How do I solve for n in this equation:

-6n-20=-2n+4 (1-3n)

-6n-20=-2n+4 (1-3n)

Solution

The bracket should be expanded

-6n-20=-2n+4-12n

Then we collect the like terms

-6n + 2n+12n = 20+4

8n=24

Now divide both sides by 8

8n/8 = 24/8

n = 3

You can now insert 3 into anywhere you see n and see how it goes

-6n-20 = - 2n + 4 (1-3n)

-6 (3) - 20 = - 2 (3) + 4[ 1-3 (3) ]

-18 - 20 = - 6 + 4 (1-9)

-38 = - 6 - 32

-38 = - 38

That's all
