Solution

The correct option is A ${x \geq 4}$
Given: $A = {x : 11 x - 5 > 7 x + 3, x ϵ R}$
$11 x - 5 > 7 x + 3$

Rule: If a term of an inequation is transferred from one side to the other side of the inequation, the sign of the term gets changed. Let's apply this rule in the above inequation.

$\Rightarrow 4 x > 8$
$\Rightarrow x > 2$

Given: $B = {x : 18 x - 9 \geq 15 + 12 x, x ϵ R}$
$\Rightarrow 18 x - 9 \geq 15 + 12 x$

Rule: If a term of an inequation is transferred from one side to the other side of the inequation, the sign of the term gets changed. Let's apply this rule in the above inequation.

$\Rightarrow 6 x \geq 24$
$\Rightarrow x \geq 4$
So $A \cap B = x \geq 4$
