(8-x)/9 =(2x+1)/3

\frac{8 - x}{9} = \frac{2 x + 1}{3}

x = \frac{5}{7}

Decimal Notation

x = 0.71428 \dots

Solution steps

\frac{8 - x}{9} = \frac{2 x + 1}{3}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(8 - x) \cdot 3 = 9 (2 x + 1)

Expand

(8 - x) \cdot 3 : 24 - 3 x

Expand

9 (2 x + 1) : 18 x + 9

24 - 3 x = 18 x + 9

Move

24

to the right side

- 3 x = 18 x - 15

Move

18 x

to the left side

- 21 x = - 15

Divide both sides by

- 21

x = \frac{5}{7}

75

\frac{( 2 + i )}{( 4 + i )}

\frac{t ^{2}}{20} + 8 = 15

1 2^{2} + 1 4^{2} = x^{2}

∣ 3 x - 1 ∣ > 14
