Question

Solve the equation 3n-3=4n+1

Answer 1

Start by getting your variables together on one side of the equal sign by subtracting the 3n from both sides. 
This leaves you with : -3 = n + 1
 
Subtract the 1 from both sides and this leaves you with the solution -4 = n

So
n = -4

Answer 2

3n - 3 = 4n + 1
Add 3 to both sides
3n = 4n + 4
Subtract 4n from both sides
-n = 4
Divide by -1 on both sides
n = -4

Hope this helps! :)
