Answer:
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.
