Question

-13x-4 AKA -13x(-4)= what???

Answer 1

you would multiply -13 times -4 and then you get 52 and it should look like this x(52) and then you just rewrite it as x=52

Answer 2

remember that negative times negative=positive
so multiply as normal

13 times 4=13 times 2 times 2=26 times 2=52

answer is 52
