Find the value of n that satisfies 2(n+1)! + 6n! = 3(n+1), where $n! = n\cdot (n-1)\cdot (n-2) \cdots 2\cdot 1$.

Murrr4er [49]

Answer:

$n = 5$

Step-by-step explanation:

Given

$2(n+1)! + 6n! = 3(n+1)!$

Required

Find n

Simplify (n + 1)!

$2(n+1)*n! + 6n! = 3(n+1)*n!$

Factorize

$n![2(n+1) + 6] = 3(n+1)*n!$

Divide both sides by n!

$2(n+1) + 6 = 3(n+1)$

Open brackets

$2n + 2 + 6 = 3n + 3$

$2n + 8 = 3n + 3$

Collect like terms

$2n - 3n = 3 -8$

$-n =-5$

Multiply both sides by -1

$n = 5$

4x + 5x + 12 = 6(x-2)<br> Math

Rashid [163]

Hi there! :)

$\large\boxed{x = -8}$

4x + 5x + 12 = 6(x - 2)

Combine like terms and distribute the coefficient outside of the parenthesis:

9x + 12 = 6(x) + 6(-2)

9x + 12 = 6x - 12

Subtract 6x from both sides:

9x - 6x + 12 = 6x - 6x - 12

3x + 12 = -12

Subtract 12 from both sides:

3x + 12 - 12 = -12 - 12

3x = -24

Divide both sides by 3:

3x/3 = -24/3

x = -8.
