Answer 2

ANSWER

(i) We have, 3x−5y−4=0

⇒3x−5y=4...(i)

Again 9x=2y+7

⇒9x−2y=7...(ii)

By Elimination Method:

Multiplying equation (i) by 3, we get

9x−15y=12...(iii)

Subtracting (ii) from (iii), we get

    9x−15y=12

    9x−2y=7

       −13y=5     

⇒y=−135

Putting the value of e qation ii), we

get

9x−2(−135)=7⇒9x+1310=7⇒9x=7−1310⇒9x=1391−10

⇒9x=1381⇒x=139

Hence, the required solution is x=139,y=−135

Here is your answer !!
