To solve the equation -2x + 10 = -30, you need to isolate the variable x.
First, subtract 10 from both sides of the equation:
-2x + 10 - 10 = -30 - 10
-2x = -40
Next, divide both sides of the equation by -2 to solve for x:
-2x/-2 = -40/-2
x = 20
Therefore, the solution to the equation -2x + 10 = -30 is D. 20.
Which is a solution to the equation
