Simplifying
2(n + 20) = 110
Reorder the terms:
2(20 + n) = 110
(20 * 2 + n * 2) = 110
(40 + 2n) = 110
Solving
40 + 2n = 110
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-40' to each side of the equation.
40 + -40 + 2n = 110 + -40
Combine like terms: 40 + -40 = 0
0 + 2n = 110 + -40
2n = 110 + -40
Combine like terms: 110 + -40 = 70
2n = 70
Divide each side by '2'.
n = 35
Simplifying
n = 35
