Answer:
Explanation:
turn the equation around to look like this so you don’t get confused:
x + (-18) = (-19)
And what you do on one side, you do to the other side
x + (-18) = -19
+18 +18
The reason we added is because if the number in the middle is the opposite we would add together to zero and vice versa if it was a positive we would subtract
So now we have
x + _ = -1
And really we can take plus and the underline away
so…
The final answer is…..
x = -1
