Consider the following from the transform command, when you converted your coverage from digitizer to UTM coordinates. If you used four ticmarks for your transformation, your output looked something like this:
Arc: transform burn burn_utm
Transforming coordinates for coverage burnn
Scale (X,Y) = (844.047,834.342) Skew (degrees) = (-0.749)
Rotation (degrees) = (-0.807) Translation = (423239.514,4600002.458)
RMS Error (input,output) = (0.012,10.274)
Affine X = Ax + By + C
Y = Dx + Ey + F
A = 843.964 B = 0.840 C = 423239.514
D = -11.888 E = 834.413 F = 4600002.458

Given this output, what would be the real-world, UTM coordinates for digitizer coordinates x = 18.123, y = 26.111?
