Final answer:
There is no solution for this system of equations.
Step-by-step explanation:
To find the value of x and y for the system of equations, we will solve them simultaneously:
1) Equation 1: y = x - 1
2) Equation 2: -x + 3/2 = -y
Let's substitute Equation 1 into Equation 2:
-x + 3/2 = -(x - 1)
-x + 3/2 = -x + 1
3/2 = 1
Since 3/2 is not equal to 1, there is no solution for this system of equations.
