What is the value of x in the solution to the following system of linear equations? y=x-1 y=2x+1 –3 –2 –1 0

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
