X - 8 = - 10

What's x

x = - 2

Step-by-step explanation:

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

x = - 2

-2

Step-by-step explanation:

x-8=-10

x=-10+8

x=-2
