I need help. what do i do and how do I solve this?

x = -11.6

-(-11.6) + 1.2 = 12.8

Isolate the variable by dividing each side by factors that don’t contain the variable.

X= -11.6

Step-by-step explanation:

Step 1 - Subtract 1.2 from both sides.
-x + 1.2 - 1.2 = 12.8- 1.2
-x = 11.6

Step 2: Divide both sides by -1.
-x 11.6

-1 -1

If u don’t understand try searching up (solving variables on both sides calculator) It gives steps : )
