Step-by-step explanation:
![y = 2x - 4](https://tex.z-dn.net/?f=y%20%3D%202x%20-%204)
![3x + y = 1](https://tex.z-dn.net/?f=3x%20%2B%20y%20%3D%201)
![y = 1 - 3x](https://tex.z-dn.net/?f=y%20%3D%201%20-%203x)
Equating,
![2x - 4 = 1 - 3x](https://tex.z-dn.net/?f=2x%20-%204%20%3D%201%20-%203x)
![2x + 3x = 1 + 4](https://tex.z-dn.net/?f=2x%20%2B%203x%20%3D%20%201%20%2B%204)
![5x = 5](https://tex.z-dn.net/?f=5x%20%3D%205)
![x = 1](https://tex.z-dn.net/?f=x%20%3D%201)
Placing it,
![y = 1 - 3( 1)](https://tex.z-dn.net/?f=y%20%3D%201%20-%203%28%20%201%29)
![y = 1 - 3](https://tex.z-dn.net/?f=y%20%3D%201%20-%203)
![y = - 2](https://tex.z-dn.net/?f=y%20%3D%20%20-%202)
Multiply each side by 2: 2(x/2) + 3(2) = 5(2) => x + 6 = 10
Subtract 6 from each side: x + (6 - 6) = 10 - 6 => x = 4
The answer is x is equal to 4.
