Answer:
The value of x in the solution to the given system of linear equation is x = -2
Step-by-step explanation:
The system of equations is given to be :
y = x - 1 .........(1)
y = 2x + 1 ........(2)
We need to solve both of these equations.
So, Putting y = x - 1 from equation (1) into equation (2)
⇒ x - 1 = 2x + 1
⇒ -x = 2
⇒ x = -2
Also, y = x - 1
⇒ y = -2 - 1
⇒ y = -3
Hence, The value of x in the solution to the given system of linear equation is x = -2
