Answer 2

Пошаговое объяснение:

$(x + 26) \times 12 = 380$

$12(x + 26) = 380$

$\frac{12(x + 26)}{12} = \frac{380}{12}$

$x + 26 = \frac{380}{12}$

$x + 26 = \frac{95}{3}$

$x + (26 - 26) = \frac{95}{3} - 26$

$x = \frac{95}{3} - 26$

$x = ( \frac{95}{3} - \frac{26 \times 3}{3} )$

$x = \frac{95}{3} + \frac{ - 78}{3}$

$x = ( \frac{95 - 78}{3} )$

$x = \frac{17}{3}$
