To solve the equation \(4x + 8 = 22\), the first operation you should perform is subtraction.
Here’s how you can break it down:
- Start with the equation: \(4x + 8 = 22\).
- To isolate the term with \(x\), subtract 8 from both sides of the equation:
\(4x + 8 - 8 = 22 - 8\), which simplifies to \(4x = 14\).
So, the first operation is subtraction.
