do you want the procedure or you just want to check which of them is the correct answer?

anonymous · Answer

Both , please ? (:

hero · Answer

Hint: Use matrices to solve

anonymous · Answer

if you just want to know which of them is the correct answer, then substitute each option in the equations and see which one satisfies all the three equations.

anonymous · Answer

don't use matrices as you are asked to use elimination method.

anonymous · Answer

So , is it the 3rd option ?

hero · Answer

You can use elimination method with matrices

anonymous · Answer

anonymous · Answer

now you should also know how to get the solution by elimination method. right?

anonymous · Answer

I think ?
