Question

Pls help

Answer 1

were you happy with the first answer? I can comment mine if needed. Just let me know. :)

Answer 2

it's really just your own opinion of which is difficult or easier but in my opinion Substitution is more difficult because you have to substitute in the different equations, and it can take more time. I personally like Elimination best because it cancels out variables and can be quicker to use. hope this helps:)
