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
Cancel 40 on the left side:
2n = 13
Divide each side of the equation by 2
2n
2

n = 6.5
Final Answer
n = 6.5
What is the Answer?
n = 6.5
