Answer:

Solving the given linear system, we get x = 1 and y = -3.

The solution set is: (1,-3)

Step-by-step explanation:

We need to solve the linear system of equations.

[tex]3x-y=6 \\y=x-4[/tex]

We can write second equation y=x-4  as: [tex]-x+y=-4[/tex]

Let:

[tex]3x-y=6--eq(1)\\ -x+y=-4--eq(2)[/tex]

Now, Adding equation 1 and 2

[tex]3x-y=6\\ -x+y=-4\\--------\\2x+0y=2\\2x=2\\x=\frac{2}{2}\\x=1[/tex]

So, we get x = 1

Now, put value of x in second equation to find value of y:

[tex]y=x-4\\Put\:x=1\\y=1-4\\y=-3[/tex]

So, we get y = -3

Solving the given linear system, we get x = 1 and y = -3.

The solution set is: (1,-3)
