##### Enter Equation or Inequality

Solve the following equation

2(n+20)=53

Solve for n

2(n + 20) = 53

Simplify by removing parentheses
Simplify 2(n + 20):
Distribute the 2 to each term in (n+20)
2 * n = (2 * 1)n = 2n
2 * 20 = (2 * 20) = 40
Our Total expanded term is 2n + 40

Our new term is
2n + 40 = 53

Simplify by removing parentheses
Our new term is
2n + 40 = 53

##### Group constants

Group our constants 40 and 53.
subtract 40 from both sides

2n + 40 - 40 = 53 - 40

2n = 13

 2n 2
 =
 13 2

n = 6.5

n = 6.5
