Solve the system by addition or substitution.
16x4y=20
y=4x4
I ask for help with this and forgot to add the problem. can anyone help me understand how to do this?
16x4y=20
4x+y=4
___________
16x4y=20
(4)(4x+y=4)
______________
16x4y=20
16x+4y=16
______________
0=4
answer: empty set
16x  4(4x4) = 20
16x  16x  16 = 20
16 = 20
It doesn't work. Anonymous is right. Empty Set.
