Oh, oh! This is such a tricky question... Guess what! <u>Both</u> of them are correct. Why? Because if we simplify 3/12, we get 1/4th! (How do you simplify?) 3/12 = 1/4 Because if we divide both "3" and "12" in 3/12 by 3, we get 1 instead of 3 and 4 instead of 12.
You first subtract 5x from both sides and end up with -3y=21-5x. In order to isolate the variable you need to divide -3 from both sides. Your equation would then be y= -7+ 5/3x.
