The solution set $\frac{3(x-2)}{7}≤\frac{5(x+4)}{9}, x \in R $ is :
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → $\left[-\frac{97}{4}, ∞\right)$
$\frac{3(x-2)}{7}≤\frac{5(x+4)}{9}$
$⇒\frac{3(x-2)}{7}-\frac{5(x+4)}{9}≤0$
$⇒27(x-2)-35(x+4)≤0$
$⇒27x-35x-54-140≤0$
$⇒-8x-194≤0$
$⇒8x≥-194$
$⇒x≥-\frac{194}{8}=-\frac{97}{4}$
