Answer:
-2
Step-by-step explanation:
x-8=-10
x=-10+8
x=-2
x = -2
x - 8 = -10
Since 8 is being subtracted from x, you need to undo that subtraction to end up with x alone. To undo a subtraction, you do the opposite operation which is addition. You must do the same operation to both sides of an equation.
Add 8 to both sides of the equation.
x - 8 + 8 = -10 + 8
