यदि (12x-6y=42) और (2x-y=t) असंगत हैं, तो (t) के लिए सही शर्त क्या है?

If (12x-6y=42) and (2x-y=t) are inconsistent, what is the correct condition for (t)?

Explanation opens after your attempt
Correct Answer

B. \(t \ne 7\)

Step 1

Concept

The first two ratios are equal, so (42/t) must be different for inconsistency. Hence, \(t \ne 7\).

Step 2

Why this answer is correct

The correct answer is B. \(t \ne 7\). The first two ratios are equal, so (42/t) must be different for inconsistency. Hence, \(t \ne 7\).

Step 3

Exam Tip

पहले दो अनुपात बराबर हैं, इसलिए असंगत होने के लिए (42/t) अलग होना चाहिए। अतः \(t \ne 7\)।
