Question

Which of the following equation (A) + 4x = -2 (B) 3y = 3 - 6 (C) – + 3 = -2 (D) – + 3 = -6

Answer 1

`y=(1)/(3)x-2`

Multiplying by 3 at both sides:

`\begin{gathered} 3y=3((1)/(3)x-2) \\ 3y=3\cdot(1)/(3)x-3\cdot2 \\ 3y=x-6 \end{gathered}`

Subtracting x at both sides:

`\begin{gathered} 3y-x=x-6-x \\ -x+3y=-6 \end{gathered}`

Then, option D is correct
