Write a real world situation that can be represented by the equation 2 (n+20) = 110.

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
