Answer:
27
Step-by-step explanation:
our equation should be: (x-13)-7=-98
First divide both sides by -7 to undo the multiplication
(x-13)-7=-98
--- ---
7 7
(x-13)=14
if you'd like you can remove the parenthesis since there isn't anything outside of them on the left side
x-13=14
now add 13 to both sides to undo the subtraction
x-13=14
+13 +13
therefore,
x=27
hope this helps!
~~~checking~~~
(27-13)-7=-98
(14)-7=-98
-98=-98
