Use addition to solve the linear system of equations. include all of your work in your final answer. 3x-y=6 and y=x-4

x = 1 and y = -3

Step-by-step explanation:

The given linear equations are,

3x - y = 6 and y = x - 4

To solve the system of equations

Let 3x - y = 6   (1)

y = x - 4

x - y = 4  (2)

(2) * -3 ⇒ -3x  + 3y = -4   (3)

(2) + (3) ⇒

3x - y = 6  

-3x  + 3y = -12

0   +2y = -6

y = -6/2 = -3

x - y = 4  

x = 4 + y = 4 + -3 = 1

x = 1 and y = -3
