Question

2n+(7n+8)= missing number n+8

Answer 1

so is it equal to n+8

Answer 2

if it is equal to n+8 this is the answer

Answer 3

Simplifying
2n + (7n + 8) = n + 8

Reorder the terms:
2n + (8 + 7n) = n + 8

Remove parenthesis around (8 + 7n)
2n + 8 + 7n = n + 8

Reorder the terms:
8 + 2n + 7n = n + 8

Combine like terms: 2n + 7n = 9n
8 + 9n = n + 8

Reorder the terms:
8 + 9n = 8 + n

Add '-8' to each side of the equation.
8 + -8 + 9n = 8 + -8 + n

Combine like terms: 8 + -8 = 0
0 + 9n = 8 + -8 + n
9n = 8 + -8 + n

Combine like terms: 8 + -8 = 0
9n = 0 + n
9n = n

Solving
9n = n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-1n' to each side of the equation.
9n + -1n = n + -1n

Combine like terms: 9n + -1n = 8n
8n = n + -1n

Combine like terms: n + -1n = 0
8n = 0

Divide each side by '8'.
n = 0

Simplifying
n = 0

Answer 4

no 2n+7n+8 () it the missing number + n+8
