Step-by-step explanation:
Solving these is quite simple; think of "a number" as a value of either n or x (depending on personal preference) then just find the operations being done based on key words;
1. Sum= addition so it is x+5
2. Decrease= subtraction so it is 11-n
3. Quotient= division so it is -9/y
4. Twice= multiply by two, minus= subtract, so it is 2n-13
61-34x98+90+21-4
We will put these in parenthesis to make it easier to read, and to mark what needs done first.
61-(34x98)+90+21-4
34x98=3,332
Now that the multiplication is done, we add and subtract.
90+21=111
61-3,332=-3271
-3271+111-4
We can reorder this to make it easier. Plus, we'll subtract -4 and -3271.
111-3275=-3164
