-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: \[ b = -18 \]
