Step-by-step explanation:


\begin{gathered} 2x\text{ - y = 1 . . .(1)} \\ 4x\text{ - 2y = 2 . . . (2)} \end{gathered}

Using elimination method:

We need the coeeficient of the letter we want to eliminate to have same coefficient

To eliminate x, we will multipkly equation (1) by 2:

2(2x) - 2(y) = 2(1)

4x - 2y = 2 . . .(3)

combinig equation (2) and (3):

4x - 2y = 2

4x -
