5-22-[-3n-2(n+5)]=-8n+2(1+4n)-21

5 - 22 - [- 3 n - 2 (n + 5)] = - 8 n + 2 (1 + 4 n) - 21

n = - \frac{12}{5}

Decimal Notation

n = - 2.4

Solution steps

5 - 22 - [- 3 n - 2 (n + 5)] = - 8 n + 2 (1 + 4 n) - 21

Expand

5 - 22 - (- 3 n - 2 (n + 5)) : 5 n - 7

Expand

- 8 n + 2 (1 + 4 n) - 21 : - 19

5 n - 7 = - 19

Move

7

to the right side

5 n = - 12

Divide both sides by

5

n = - \frac{12}{5}

\frac{x}{5} + 1 = \frac{2 x}{3}

x, 5 x = 4 y

2 - (3 x - 5) = 4 - 2 x + 3 - x

\frac{- 3}{7} x = \frac{5}{4}

9 x - 8 = 2 x + 20
