To solve for d, we need to isolate it on one side of the equation.
Starting with the given equation:
5d = 2d - 18
We want to get rid of the 2d on the right side, so we can subtract 2d from both sides:
5d - 2d = 2d - 18 - 2d
This simplifies to:
3d = -18
To solve for d, divide both sides of the equation by 3:
3d/3 = -18/3
This simplifies to:
d = -6
Therefore, the value of d is -6.
5d=2d-18
