    Use the following theorems,
    2x+5=x+z (1)
    2x-5=x+y (2)
    Add these equations,
    4x=2x+y+z
    Subtract by 2x,
    2x=y+z
    But,
    x+y+z=180
    Thus, (substitute)
    x+2x=3x=180
    Thus, x=60

    Thus, in the first equation,
    120+5=60+z,z=65
    Thus,in the second equation,
    120-5=60+y,y=55
    Thus, (x,y,z)=(60,55,65)
    Q.E.D.
