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
