Question

4. Solve for y 2x - y = -8

Answer 1

`\begin{gathered} 2x-y=-8 \\ Subtract\text{ 2x from both sides of the equation} \\ 2x-2x-y=-8-2x \\ -y=-8-2x \\ \text{Multiply all through by -1} \\ \text{This eliminates all negative signs, including the negative in front of y} \\ y=8+2x \\ OR \\ y=2x+8 \end{gathered}`

The correct option is y = 2x + 8
