(2n+2)/8 = n/3

\frac{2 n + 2}{8} = \frac{n}{3}

n = 3

Solution steps

\frac{2 n + 2}{8} = \frac{n}{3}

Apply fraction cross multiply: if

\frac{a}{b} = \frac{c}{d}

then

a \cdot d = b \cdot c

(2 n + 2) \cdot 3 = 8 n

Expand

(2 n + 2) \cdot 3 : 6 n + 6

6 n + 6 = 8 n

Move

6

to the right side

6 n = 8 n - 6

Move

8 n

to the left side

- 2 n = - 6

Divide both sides by

- 2

n = 3

\frac{a}{3} - 4 = 3

3.9 x - 2.1 = 11.2 x + 51.7

x, 4 g + r = 2 r - 2 x

23 (3 x + 9) = - 2 (2 x + 6)

2 n - 21 = \frac{n}{4}
