Answer:
-2.5
Step-by-step explanation:
Simplifying
20k + 50 = 0
Reorder the terms:
50 + 20k = 0
Solving
50 + 20k = 0
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '-50' to each side of the equation.
50 + -50 + 20k = 0 + -50
Combine like terms: 50 + -50 = 0
0 + 20k = 0 + -50
20k = 0 + -50
Combine like terms: 0 + -50 = -50
20k = -50
Divide each side by '20'.
k = -2.5
