Answer:
(1,-3)
Step-by-step explanation:
Subtract 3x to get y by itself. *Not needed for second equation*
then you set both equations equal to each other
x-4=-3x is the equation
Subtract x from the left side so -4=-4x
divide both sides by -4
x=1
Then plug that value into x in one of the y='s
(I recommend plugging it into the first equation because that is easier)
y=-3(1)
y=-3
