Question

What is the value of n in the equation (2n + 4) + 6 = –9 + 4(2n + 1)?

Answer 1

Isolate the variable by dividing each sides by factors that don't contain the variable.

Exact form: n =
`(5)/(2)`

Answer 2

n = 15/6

Explanation:

Step 1: Distribute

2n + 4 + 6 = -9 + 8n + 4

Step 2: Combine like terms

2n + 10 = 8n - 5

Step 2: Isolate n's

10 = 6n - 5

15 = 6n

n = 15/6
