How can I learn elimination better?

Answers

Best thing I think you should do is to go to your teacher for clarification of any doubts and practise as many example and show it to your teacher or anyone who knows it better for approval.

To be able to eliminate, you have to make a variable have the same COEFFICIENTS but OPPOSITE SIGNS. Then solve for the other ( non eliminated) variable. After that, substitute its value to the original equation and solve now for the eliminated variable.
