Answer:
y = 1/3x - 4
Explanation:
Lol lemme just write out the steps and if you're confused just comment and i'll get back to u.
x - 3y = 12
-x.........-x
-3y = -x + 12
*-1...........*-1
3y = x - 12
/3........../3
y = 1/3x - 4
And that is the equation in fully simplified slope/intercept form. I hope this helps!
