Answer:
y = -3x + 4
Step-by-step explanation:
sorry im late
but all you have to do is isolate the y
so to do that we have to get rid of the 3x
3x + y = 4
in order to do that we have to subtract 3x from both sides of the equal sign since it is positive and being added to the y
-3x -3x
and now y is isolated
