असमानता \(2x+5\le x+12\) का हल क्या है?
What is the solution of the inequality \(2x+5\le x+12\)?
Explanation opens after your attempt
A. \(x\le 7\)
Concept
Subtracting (x) from both sides gives \(x+5\le 12\), so \(x\le 7\). Isolating the variable is the key step.
Why this answer is correct
The correct answer is A. \(x\le 7\). Subtracting (x) from both sides gives \(x+5\le 12\), so \(x\le 7\). Isolating the variable is the key step.
Exam Tip
दोनों पक्षों से (x) घटाने पर \(x+5\le 12\), इसलिए \(x\le 7\)। चर को अकेला करना मुख्य कदम है।
