Question

If $2x+5\le 3$, then

• A. $2x+7\le 5$
• B. $2x+3\le 0$
• C. $2x+10\le 7$

Answer 1

The correct option is A $2x+7\le 5$

Given, $2x+5\le 3$
Concept: We can add the same number on both the sides of an inequality.
$\therefore$ By observing the options, we need to add or subtract the same number on both sides of the inequality.

$\therefore$ Adding $2$ on both sides of the inequality,

$\Rightarrow 2x+5+2\le 3+2$
$\Rightarrow 2x+7\le 5$
For the rest of the options, we cannot add or subtract the same number on both the sides of $2x+5\le 3$ to get any other options.
