Question

(х+5)*8=50 пожалуйста помогите.

Answer 1

Решение:

$8(x + 5) = 50$

$\frac{8(x + 5)}{8} = \frac{50}{8}$

$x + 5 = \frac{50}{8}$

$x + 5 = \frac{25}{4}$

$x + (5 - 5) = \frac{25}{4} - 5$

$x = \frac{25}{4} - 5$

$x = ( \frac{25}{4} - \frac{5 \times 4}{4} )$

$x = \frac{25}{4} + \frac{ - 20}{4}$

$x = ( \frac{25 - 20}{4} )$

x = 5/4= 1 1/4 = 1,25

Answer 2

Пошаговое объяснение:

$(x + 5) \times 8 = 50 \\ 8x + 40 = 50 \\ 5x = 50 - 40 \\ 8x = 10 \div 8 \\ x = \frac{5}{4} = 1 \frac{1}{4} = 1.25$
