Solve the system \(6x+5y=43\) and \(4x-5y=7\) by elimination. Find \(x\).समीकरण-समूह \(6x+5y=43\) और \(4x-5y=7\) को विलोपन (elimination) विधि से हल कीजिए। \(x\) का मान ज्ञात कीजिए।
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(x=5\)\(x=5\)
Add the equations: \((6x+5y)+(4x-5y)=43+7\Rightarrow 10x=50\Rightarrow x=5\).दोनों समीकरण जोड़ें: \((6x+5y)+(4x-5y)=43+7\Rightarrow 10x=50\Rightarrow x=5\)।
