Step-by-step Solution
Solve the equation \( 2x-7 \geq 9+7 \).
Solve the inequality by following steps:
- step0: Solve for \(x\):
\(2x-7\geq 9+7\)
- step1: Add the numbers:
\(2x-7\geq 16\)
- step2: Move the constant to the right side:
\(2x\geq 16+7\)
- step3: Add the numbers:
\(2x\geq 23\)
- step4: Divide both sides:
\(\frac{2x}{2}\geq \frac{23}{2}\)
- step5: Divide the numbers:
\(x\geq \frac{23}{2}\)
The solution to the inequality \(2x-7 \geq 9+7\) is \(x \geq \frac{23}{2}\).
Therefore, the correct answer is A. \(x \geq 8\).
Quick Answer
The correct answer is A. \(x \geq 8\).
