how do u answer this question it has to many numbers.​

Answer 1

n = 3

Explanation:

9{n+2(n-2)} = 45

Start with the numbers on the inner most pair of parentheses

Multiply (n-2) by 2

9[n+2n-4] = 45

Add what is inside the parentheses

9[3n-4] = 45

Multiply

27n-36 = 45

Add 36 to both sides

27n = 81

Divide both sides by 27

n = 3
