Question

I don't wont this to be done for me I would like to have help on how you do it .

Answer 1

3x+5x ? 8y+3y ? 2n-3n ? 7z-10z ?

There is a concept called the degree of a variable.  the variable is the letter (x,y,n,z,etc.)  you can only add/subtract/multiply/divide common variables.

x's to x's etc.

if there is a power that counts too.

x^2 to x^2.

I hope this helps
