Here Is The Solution We Found (But Others May Exist):
Step-by-Step Solution
1. Start With What Is Easiest
The equation C / 4 = 3 is straightforward. We multiply both sides by 4 to isolate C:
C = 3 × 4 = 12
2. Use This Value To Advance
Now we move to B × C = 84. Substituting C with 12 gives us:
B = 84 / 12 = 7
3. Work Backwards To Find A
With A + B = 15 and B = 7:
A = 15 − 7 = 8
4. Finally, Find D
The equation B + D = 18 now becomes:
D = 18 − 7 = 11
Final Result
The value of D is 11.
