Answer 1

To solve the equation \(-2x + 10 = -30\), follow these steps:

1. Start with the original equation:
\[
-2x + 10 = -30
\]

2. Subtract 10 from both sides to isolate the term with \(x\):
\[
-2x = -30 - 10
\]
\[
-2x = -40
\]

3. Divide both sides by -2:
\[
x = \frac{-40}{-2}
\]
\[
x = 20
\]

Thus, the solution to the equation \(-2x + 10 = -30\) is:
\[
\boxed{20}
\]
