X = - 10
Because it is the "absolute value" of "10"
Here's why
-X - 10 = 0, right?
So, now we have to add a positive 10 to each of our sides to get one step closer to our answer
-X + 10 = 0 ⬅️cancel this
0 + 10 = 10 ⬅️keep this
We can multiply by a negative 1 (-1)
10 (-1) = - 10
0 (-1) = - 0
So that's how we found out that X = - 10
