To solve the equation \(-4 + 2b = -40\) using inverse operations, we will isolate the variable \(b\). Here are the steps:
-
Add 4 to both sides to eliminate the -4 from the left side: \[ -4 + 2b + 4 = -40 + 4 \] This simplifies to: \[ 2b = -36 \]
-
Divide both sides by 2 to solve for \(b\): \[ \frac{2b}{2} = \frac{-36}{2} \] This simplifies to: \[ b = -18 \]
So, the solution is \(b = -18\).
For visual representation, you may want to use Sketchpad or another graphing tool to illustrate the steps, but here's a simple breakdown you could present:
- Start with the equation: \(-4 + 2b = -40\)
- Show adding 4 to both sides: \(2b = -36\)
- Show dividing both sides by 2: \(b = -18\)
If you're using software like Sketchpad, you can create a visual representation by plotting the steps, showing the manipulation of the equation at each stage.
