Answer: n = 31.66666667
Explanation:
Add '-12n' to each side of the equation.
500 + -12n = 120 + 12n + -12n
Combine like terms: 12n + -12n = 0
500 + -12n = 120 + 0
500 + -12n = 120
Add '-500' to each side of the equation.
500 + -500 + -12n = 120 + -500
Combine like terms: 500 + -500 = 0
0 + -12n = 120 + -500
-12n = 120 + -500
Combine like terms: 120 + -500 = -380
-12n = -380
Divide each side by '-12'.
n = 31.66666667
Simplifying
n = 31.66666667
