Question

1/3 x + y = 4 solve for y

Answer 1

y=4
hope this helps :)

Answer 2

The simplified answer to the equation is $y=-\frac{1}{3}x+4$

First, subtract $\frac{1}{3}x$  on both sides.

$y=-\frac{1}{3}x+4$

You have isolated $y$ by itself, and the equation can't be simplified further, so $y=-\frac{1}{3}x+4$  is your answer.
