Step 2: Apply the principle of equality

To isolate d, we must perform the same operation on both sides to maintain balance. Since d is added to 17298, the inverse operation is subtraction:
Subtract 17298 from both sides
17298 + d − 17298 = 20 − 17298

Step 3: Simplify both sides

On the left side: 17298 − 17298 cancels out, leaving just d
On the right side: 20 − 17298 = −17278

This yields:
d = −17278
