Answer:
X=-2
Step-by-step explanation:
You start with adding 7 to the side with -9 to get the (x) alone. Then you have x=-2.
x = -2
Adding two negative numbers is easy: you're just adding two "negative" arrows, so it's just like "regular" addition, but in the opposite direction. For instance, 4 + 6 = 10, and –4 – 6 = –4 + (–6) = –10.
