Find the value of N, given that:
1. Either A = B/3 or A = G + 3. 2. Either B = I - 4 or B = E + 4. 3. Either C = J + 2 or C = F*3. 4. Either D = G*4 or D = E/3. 5. Either E = J - 1 or E = D/4. 6. Either F = B*2 or F = A - 4. 7. Either G = F + 1 or G = I - 3. 8. Either H = A/2 or H = C*3. 9. Either I = H + 3 or I = D/2. 10. Either J = H - 2 or J = C*2.*** The or definition is exclusive for each of the ten parts.
