You need to solve for each value x and y. These two equations provide the intersection of both whereby
y=2x-4 and y=x-1
this gives us, by replacing y in the first equation with x-1 = 2x-4
subtract the left side x from the right side gives us - 1 = x - 4
subtracting known values x = 3
verfy the results gives us 2 (3) - 4 = y
2 = y
also 3 - 1 = y
2 = y
so you wind up with x = 3 and y = 2
