Answer:
y = 2 - 1/2x
Step-by-step explanation:
So we are given the equation 3x + 6y = 12 and are ask to find y.
To find y you must isolate it first.
3x + 6y = 12
(Subtract 3x to isolate the y term)
6y = 12 - 3x
(Divide both sides by 6 to isolate the variable)
y = 2 - 3/6x
(Simplify)
y = 2 - 1/2x
And that is your answer since there is a second variable.
(A) is the correct answer choice:)
