To solve for 'd', you need to isolate the variable on one side of the equation. Here's how you can do that:
5d = 3d - 18
Subtract 3d from both sides of the equation:
5d - 3d = 3d - 3d - 18
This simplifies to:
2d = -18
Now, divide both sides of the equation by 2:
2d/2 = -18/2
The 2's cancel out on the left side, and you're left with:
d = -9
Therefore, the solution is d = -9.
5d=3d-18
