Question

Решите уравнение......

Answer 1

Ответ: -3.4

Объяснение:

17х+26/4х+3=3 По пропорции

3(4х+3)=17х+26

12х-17х+9-26=0

-5х=17

х=-17/5

х=-3.4

Answer 2

Ответ:

$- 3.4$

Объяснение:

$\frac{17x + 26}{4x + 3} - 3 = 0 \\ \frac{17x + 26}{4x + 3} - \frac{3(4x + 3)}{4x + 3} = 0 \\ \frac{17x + 26 - 12x - 9}{4x + 3} = 0 \\ \frac{5x + 17}{4x + 3} = 0 \\ 5x + 17 = 0 \\5x = - 17 \\ x = - 3.4 \\ 4x + 3 \: not = 0 \\ 4x \: not = - 3 \\ x \: not = - \frac{3}{4}$
