Question

Найдите корень уравнения

Answer 1

$\frac{x + 2}{8} = \frac{x + 35}{32} \\ \frac{4x + 8}{32} = \frac{x + 35}{32} \\ 4x + 8 = x + 35 \\ 4x - 1x = 35 - 8 \\ 3x = 35 - 8 \\ 3x = 27 \\ x = 27 \div 3 \\ x = 9$

_______________

5х-19 / 9 = - 6
5х-19 / 9 = - 6/1
5х-19 / 9 = - 54/9
5х-19=-54
5х=-54+19
5х=-35
х=-35 : 5
х=-7

Answer 2

1)

$\frac{x + 2}{8} = \frac{x + 35}{32}$

общая дробь 32

$4(x + 2) = x + 35$

$4x + 8 = x + 35$

$4x - x = 35 - 8$

$3x = 27$

$x = 27 \div 3$

$x = 9$

Ответ : 9

2)

$\frac{5x - 19}{9} = - 6$

общая дробь 54

$6(5x - 9) = - 6 \times 9$

$30x - 54 = - 54$

$30x = - 54 + 54$

$30x = 0$

$x = 0 \div 30$

$x = 0$

Ответ : 0
