MCQ
The solution set of 6x - 1 > 5 is :
  • A
    $\{x: x>1, x \in N\}$
  • B
    $\{x: x>1, x \in R\}$
  • C
    $\{x: x<1, x \in N\}$
  • D
    $\{x: x<1, x \in W\}$
✓

Answer

(b) $\{x: x>1, x \in R\}$
Explanation: $6 x-1>5$
$\begin{array}{l}\Rightarrow 6 x-1+1>5+1 \\ \Rightarrow 6 x>6 \\ \Rightarrow x>1\end{array}$
Hence the solution set is $\{x: x>1, x \in R\}$
