Answer

y = (x-5) / 3

Work Step by Step

1. First we must the write the equations at y = 3x + 5. 2. Then we solve the equation for x in terms of y, doing this will require to you to subtract 5 from both sides and then dividing by 3. This will give us x = (y - 5) / 3. 3. Now switch all the x to y variables and all y to x variables. 4. Doing so will give us y = (x-5) / 3.
