### How do justify each step in math like a problem 5n 4 9n5n 20 9n?

depends on what is imbetween all of those numbers and variables.
If it as all + or all - or wat!
But pretty much it just means to show your work! lets say the
problem is 5n+4+9n times 5n - 20 +9n you just show your work follow
the Order of Operations though
9n times 5n= 45n problem= 5n+4+45n-20+9n add alike terms and
variables
5n+45n+9n= 59n 4-20= -16 problem= 59n-16 and that's as far as
you can go for now
