Answer:

Luana is correct

Explanation:

Hello!

According to the question, we are supposed to check whether Luana is right

Oops you made a typo

It's supposed to be -x+2 = --10 not -x+2--10

-x+2 = --10

Add values

When, x = 12

-(+12) + 2 = -10

-12 + 2 = -10

Calculate

-10 = -10

She is correct

When solving

−x+2=−10

Step 1: Subtract 2 from both sides.

−x+2−2=−10−2

−x=−12

Step 2: Divide both sides by -1.

−x/−1 = −12/−1

x=12

So, she's correct
