-40+2n=4n-8(n+8)

- 40 + 2 n = 4 n - 8 (n + 8)

n = - 4

Solution steps

- 40 + 2 n = 4 n - 8 (n + 8)

Expand

- 8 (n + 8) : - 8 n - 64

- 40 + 2 n = 4 n - 8 n - 64

Add similar elements:

4 n - 8 n = - 4 n

- 40 + 2 n = - 4 n - 64

Move

40

to the right side

2 n = - 4 n - 24

Move

4 n

to the left side

6 n = - 24

Divide both sides by

6

n = - 4

z^{2} + 6 z - 7 = 0

\frac{1}{\frac{1}{15} + \frac{1}{10} + \frac{1}{30}}

3 (t)^{2} - 27 = 0

15 = 5 + 4 (2 d - 3)

\frac{8 !}{( 8 - 6 ) ! 6 !}
