61x

The answer is 61x It is 61x because Order of Operations say Pemdas but since we don't have a P(parentheses) , E (Exponents) , and M (multiplication) , We are now left with A and S we add 20x, 40x, and 21x we get 81x we now have no more addition so now we have subtraction left so we subtract 20x (same as -20x) from 81x and then we are left with 61x
