Step-by-step explanation:
![\begin{gathered} 2x\text{ - y = 1 . . .(1)} \\ 4x\text{ - 2y = 2 . . . (2)} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/6c1v0elxq53cs40nztqq91fbqo5m0syb7k.png)
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 -
