Explanation:
4x-3y= 11
4(5)-3(z) = 11
20-3z = 11
20-11 = 3z

प्रश्न :- यदि (5, z) 4x - 3y = 11 का हल है, तो z का मान ज्ञात कीजिए।* 1️⃣ 5
2️⃣ 19/3
3️⃣ 31/3
4️⃣ 3
उतर :-
चूंकि (5, z) दिए हुए समीकरण 4x - 3y = 11 का हल है l
अत , x = 5 और y = z रखने पर,
→ 4x - 3y = 11
→ 4 * 5 - 3 * z = 11
→ 20 - 3z = 11
→ 3z = 20 - 11
→ 3z = 9
→ z = 9/3
→ z = 3 (Option 4) (Ans.)
इसलिए z का मान 3 होगा ll
