Step-by-step explanation:
The given equations are
10x + 3y = 75. ....(i)
6x - 5y = 11. ....(ii)
Multiplying (i) by 5 and (ii) by 3, we get
50x + 15y = 375. .... (iii)
18x + 15y = 33. ..... (iv)
Adding both
=> 68x = 408
=> x = 408/68
=> x = 6
Putting x = 6 in (i), we get
=> 10(6) + 3y = 75
=> 60 + 3y = 75
=> 3y = 75 - 60
=> 3y = 15
=> Y = 5
Hence, x = 6 and y = 5
