378=18z
21=z (378/18)

x/6=19
x=114 (19 times 6)

27d=945
d=35 (945/27)

17c=1479
c=87(1479/17)

always get the varible by its self (x,z,d,c, etc)
by doing the inverse operations (multiphy when varible is divided as in problem 1)

378 = 18z
21 =z

x/6 = 19
x = 6*19
x = 114

27d = 945
d = 35

1479 = 17c
87 = c
