(6-x)/4 = x/8

\frac{6 - x}{4} = \frac{x}{8}

x = 4

Solution steps

\frac{6 - x}{4} = \frac{x}{8}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(6 - x) \cdot 8 = 4 x

Expand

(6 - x) \cdot 8 : 48 - 8 x

48 - 8 x = 4 x

Move

48

to the right side

- 8 x = 4 x - 48

Move

4 x

to the left side

- 12 x = - 48

Divide both sides by

- 12

x = 4

x, m (5 - x) = 2 - y

x, 3 x - y + 2 z = 12

\frac{x}{( 2 c + 1 )} + \frac{( 2 c + 1 )}{( 2 c )} = \frac{21}{12}

(x - 3) 2 - (2 x + 5) 2 = - 16

0.2 x - 3 x - 3 = x - 2 x - 1
