What is the solution set for [-x]=10

Mathematics
1 answer:
Lesechka [4]3 years ago

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
