Here is your answer

B. (12,30)

REASON:

Given,

y= 2x+6 .......(i)

3x-y= 6 .......(ii)

Putting the value of y from eq.i in eq.ii we get

3x-(2x+6)=6

3x-2x-6=6

=6+6

x=12

Putting x=12 in eq.i we get

y= 2x+6

y= 2×12+6

y= 24+6

y= 30

So,

\bold{x=12 and y= 30}

Hence answer is (12,30) in which x=12 and y=30
