Answer:

for substitution, make one of the alphabet (x or y) a subject from one of the equation and substitute it in the other equation.

for elimination, name the equations as 1 and 2, and try to find a possible equation 3 then substitute equation 3 into equation 1 or 2 and you'll finally get your answer

should I solve it?
