Answer:
Simplifying
5n + -9 + 6 = -20
Reorder the terms:
-9 + 6 + 5n = -20
Combine like terms: -9 + 6 = -3
-3 + 5n = -20
Solving
-3 + 5n = -20
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '3' to each side of the equation.
-3 + 3 + 5n = -20 + 3
Combine like terms: -3 + 3 = 0
0 + 5n = -20 + 3
5n = -20 + 3
Combine like terms: -20 + 3 = -17
5n = -17
Divide each side by '5'.
n = -3.4
Simplifying
n = -3.4
