5d + 20 = -30

1 answer

To solve the equation 5d + 20 = -30, we need to isolate the variable "d" on one side of the equation.

First, subtract 20 from both sides of the equation:

5d + 20 - 20 = -30 - 20

This simplifies to:

5d = -50

Next, divide both sides of the equation by 5 to solve for "d":

(5d)/5 = -50/5

This simplifies to:

d = -10

Therefore, the solution to the equation 5d + 20 = -30 is d = -10.
