Question

решите уравнение по математике

Answer 1

$2(x + 3) = 6 \times 5 \\ 2(x + 3) = 30 \\ x + 3 = 30 \div 2 \\ x + 3 = 15 \\ x = 15 - 3 \\ x = 12$

Answer 2

Ответ:

x = 12

Пошаговое объяснение:

$\frac{6}{x+3}=\frac{2}{5}\\\\x+3=6:\frac{2}{5}\\\\x+3=6*\frac{5}{2}\\\\x+3=\frac{30}{2}\\\\x+3=15\\x=15-3\\x=12$
