x = 3
y = 9
Step-by-step explanation:
3x - y = 0....(i)
x - y + 6 = 0
=> x - y = - 6....(ii)
Subtract (i) and (ii)
=>
3x - y = 0
- x ± y = ± 6
=> 2x = 6
=> x = 6/2
=> x = 3
Put the value of x in (i)
3x - y = 0
=> 3(3) - y = 0
=> 9 - y = 0
=> - y = -9
=> y = 9
Hence the value of x and y are 3 and 9 respectively.
hope it helps.
