What is the solution of (8-2(3x+1)\leq 0)?
Explanation opens after your attempt
A. \(x\geq 1\)
Concept
Simplifying gives \(8-6x-2\leq 0\), that is \(6-6x\leq 0\). Then \(-6x\leq -6\) gives \(x\geq 1\).
Why this answer is correct
The correct answer is A. \(x\geq 1\). Simplifying gives \(8-6x-2\leq 0\), that is \(6-6x\leq 0\). Then \(-6x\leq -6\) gives \(x\geq 1\).
