Question

Solve the equation for the letter y: -2x + 4y = 8

y = 2x + 8

y = 4(2x + 8)

y = -2x - 8

none of the above

Answer 1

-2x + 4y = 8
-2x -2x
4y = -2x + 8
divide both sides by 4
y = -1/2x + 2 is your answer

Answer 2

none of the above

Answer 3

Actually you would add the 2x so

-2x + 4y = 8
+2x +2x
4y=2x+8
y=2/4x +8/4
y=1/2x+2

According to your choices it's none of the above.
