Answer:
join the y-related together and the others together
ie -7+1/3y
thats the shortest form one can drill down to, so that should be the answer
Step-by-step explanation:
To solve for y, isolate the variable to one side.
9x+3y=4
-9x -9x
~~~~~~~~
3y= -9x+4
~~~~~~~~
3y= -9x+4 (Divide both sides by 3)
y=-3x+4
