Hey!!

10x + 3y = 75 ----------- ( 1 )

6x - 5y = 11 -------------- ( 2 )

From eq'n ( 1 )

10x + 3y = 75

=> 3y = 75 - 10x

=> y = ( 75 - 10x / 3 ) --------- ( 3 )

Substitute eq'n ( 3 ) in eq'n ( 2 )

6x - 5y = 11

=> 6x - 5 ( 75 - 10x / 3 ) = 11

=> 18x - 375 + 50x = 33

=> 68x = 33 + 375

=> 68x = 408

=> x = 408 / 68

=> x = 6

From eq'n ( 3 )

y = ( 75 - 10x / 3 )

=> y = 75 - 10 ( 6 ) / 3

=> y = 75 - 60 / 3

=> y = 15 / 3

=> y = 5

Therefore the value of x = 6 and y = 5

Hope it helps☺☺
