Answer 1

`\begin{gathered} -4x\text{ - 2y = -2 -----(1)} \\ x\text{ - 2y = 9}-------(2) \\ \text{Then equation(1) - (2)} \\ -4x\text{ - 2y = -2} \\ -(x\text{ - 2y = 9}) \\ -4x\text{ -}x\text{ }=\text{ -2-9} \\ -5x\text{ = -11} \\ x\text{ = }(-11)/(-5)\text{ = }(11)/(5) \\ \text{put }x\text{ into equation(1)} \\ -4x\text{ - 2y = -2 } \\ -4((11)/(5))\text{ - 2y = -2} \\ (-44)/(5)\text{ - 2y = -2} \\ -2y\text{ = }(44)/(5)\text{ - 2} \\ -2y\text{ = }(34)/(5) \\ y\text{ = }((34)/(5))/(-2) \\ y\text{ =}(-34)/(10)\text{ = }(-17)/(5) \end{gathered}`
