Question

How do you solve `3n - 3 = 4 n + 1`?

Answer 1

`n =-4`

Explanation:

Bring all numbers to one side, and the variables to the other by

(Note that there are two ways to do this)

1. Add 3 to both sides to bring all numbers to the right:

`rarr 3n = 4n + 4`

Subtract `4n` on both sides to bring all variables to the left:

`rarr -1n = 4`

And since `n` is a negative, you want to make it a positive by either multiplying or dividing by `-1`

`rarr n = -4`

1. Subtract `3n` on both sides to bring all variables to the right:

`rarr -3 = n +1`

And then subtract `1` on both sides to bring all numbers to the left -

`rarr -4 = n`
