Question

solve the pair of equations by reducing them to a pair of linear equation 7x-2y/xy=5 and 8x+7y/xy=15 ​

Answer 1

Step-by-step explanation:

7x-2y/xy=5

TAKE 5 ON THAT SIDE AS WELL

7x-2y/xy-5=0

LCM=xy

7x × y

2y × x

5 × xy

WE GET

7xy-2xy-5xy/xy=0

0/xy=0

0=0

Same thing for other equation as well
