Question

Solve :
$\frac{2x+1}{3}+15\le 17;x\in W$

• A. {0, 1, 2}
• B. {1, 2}
• C. {0, 1}
• D. {0, 2}

Answer 1

The correct option is A {0, 1, 2}

Given, $\frac{2x+1}{3}+15\le 17$
$\Rightarrow 2x+1+45\le 51$
$\Rightarrow 2x+46\le 51$
$\Rightarrow 2x\le 5$
$\Rightarrow x\le 2.5$
Since $xϵW$
So, $x=\{0,1,2\}$
