To solve the equation, we need to isolate the variable x. We can do that by adding 2x to both sides of the equation and by subtracting 30 from both sides:

-2x + 10 = -30

Adding 2x to both sides:

10 = 2x - 30

Adding 30 to both sides:

40 = 2x

Dividing both sides by 2:

20 = x

Therefore, 20 is the solution to the equation -2x + 10 = -30.
