Week 3 Problem F

Theo made an elaborate code to remember the 10-digit combination to his bicycle lock. This is the code he came up with: A-K-B-J-C-H-D-G-E-F. In his code, each letter stands for a different digit (0-9). To find the combination, use the clues below to figure out what digit is represented by each letter. When two letters are written together without an operation symbol, they represent a tens digit and a ones digit.
D + D + D = F
B / H = K
H + H = B
D x H = CK
G + B + E = F + A + C
A x H = KE
J + A = CC
J / D = K
F x D = KG
D / J = H/B
What is the 10-digit combination to Theo's bicycle lock?

A quick note to problem solvers: I do not write these problems and will post the answers once given to me.
