A * [(B + C)(D - E) - F(G*H) ] / J = 10
Knowing that each variable is a unique, single-digit, nonzero number, and that C - B = 1, and H - G = 3, what is the number ABCDEFGHJ, where each letter is a digit? For example, if A = 4, B = 2, and C = 7, ABC would equal 427.
Please solve.

ABCDEFGHJ = 267953148
C = 7 = B + 1
H = 4 = G + 3
A* [(B + C)(D - E) - F(G*H) ] / J
= 2*[(6 + 7)*(9 - 5) - 3 * 1 * 4]/8
= 2 *[ 13 * 4 - 12] /8
= 2 * 40/8
= 10 ...... QED
