x = 4 y = - 1
Step-by-step explanation:
if you multiply - 3 by 4 it equals - 12 then add - 1 to get - 13 for the first equation.
for the second equation you multiply 3 by 4 to get 12 and multiply 4 by - 1 to get - 4 then you add them together to get 8. start with a process of elimination by substituting each eqation with 0.
