XDDD
OpenStudy (karon86):
It's okay. I don't either XD
OpenStudy (karon86):
I substituted y for (-12+3x)
OpenStudy (karon86):
And I have 3x-(-12x+3x)=12
But if I was to continue to solve I wouldn't get the answer
OpenStudy (karon86):
I meant y for (-12+3x)

Hint :-
3x-y=12, take both side to the power 2
\(\Large 2^{3x-y}=2^{12}\)
