(2x-8)/3 =(x+7)/7

\frac{2 x - 8}{3} = \frac{x + 7}{7}

x = 7

Solution steps

\frac{2 x - 8}{3} = \frac{x + 7}{7}

Apply fraction cross multiply: if

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

then

a \cdot d = b \cdot c

(2 x - 8) \cdot 7 = 3 (x + 7)

Expand

(2 x - 8) \cdot 7 : 14 x - 56

Expand

3 (x + 7) : 3 x + 21

14 x - 56 = 3 x + 21

Move

56

to the right side

14 x = 3 x + 77

Move

3 x

to the left side

11 x = 77

Divide both sides by

11

x = 7

24 x^{3} y^{2} + 54 x

2 ∣ x + 7 ∣ = 12

- 1 (4 + x) = 6

- x^{2} - 9 x - 20 = 0

0.86 - 11.8 g = - 2.92 - 12 g
