Question

7d-8=3d-8
one solution,no solution, or infinitely solutions

Answer 1

To solve the equation \( 7d - 8 = 3d - 8 \), we can isolate the variable \( d \):

1. Start by simplifying the equation:
\[
7d - 8 = 3d - 8
\]

2. Next, add 8 to both sides:
\[
7d = 3d
\]

3. Now, subtract \( 3d \) from both sides:
\[
7d - 3d = 0
\]
\[
4d = 0
\]

4. Finally, divide both sides by 4:
\[
d = 0
\]

Since we found a specific solution \( d = 0 \), the equation has one solution.
