Question

-4+2b=-40 solve using inverse operations

Answer 1

To solve the equation \(-4 + 2b = -40\) using inverse operations, follow these steps:

1. **Add 4 to both sides** to isolate the term with \(b\):
\[
-4 + 2b + 4 = -40 + 4
\]
This simplifies to:
\[
2b = -36
\]

2. **Divide both sides by 2** to solve for \(b\):
\[
\frac{2b}{2} = \frac{-36}{2}
\]
This simplifies to:
\[
b = -18
\]

So the solution is:
\[
b = -18
\]
