Question

X + 19 = -18 what would this be

Answer 1

You want to isolate X by itself.

X + 19 = -18. To isolate, you'd want to subtract 19 from both sides.
X + 19 - 19 = -18 - 19.
19 - 19 is 0. So that gives you X = -18 - 19.
-18 - 19 is -37.
So, X = -37.

Answer 2

X would be -37. since youll subtract the 19 from both sides to get x=-37
