Can you replace alphabets by the numbers to make all the below equations true?

ZY = XZ - WV

UT = YV - ST

WY = ZU - RZ

QX = PX - QV

QL = LQ - WP

SV = XT - YR

Note: You can using only 8 digits. (i.e. more than one alphabets will be mapped to same numerical value)

Z = Y = P =6

X =7

W = S = 1,

V=0 ,

U = R = T = 4,

Q=3,

L=5

Now we can rewrite the equations as :

66 = 76 - 10

44 = 60 - 14

16 = 64 - 46

37 = 67 - 30

35 = 53 - 16

10 = 74 - 64
