Answer 2

Answer : (2,1) is a solution of the system.

Step-by-step explanation :

As we are given that:

y = 3x-5 ..........(1)

y = x-1 ..........(2)

Now equating equation 1 and 2, we get the value of 'x'.

3x-5 = x-1

3x-x = -1+5

2x = 4

x = 4/2

x = 2

Now put the value of 'x' in equation 2, we get the value of 'y'.

y = x-1

y = 2-1

y = 1

Thus, the value of x = 2 and y = 1 that means (2,1) is a solution of the system.

Hence, the (2,1) is a solution of the system.
