Question

8000:(5x:10)+20=25-10

Answer 1

Ответ:

$800 0 \div (5x \div 10) + 20 = 25 - 10 \\ 8000 \div ( \frac{5}{10}x) + 20 = 10 \\ 8000 \div ( \frac{1}{2}x) + 20 = 15 \\ 8000 \div \frac{x}{2} + 20 = 15 \\ 8000 \times \frac{2}{x} + 20 = 15 \\ \frac{16000}{x} + 20 = 15 \\ \frac{16000}{x} = - 5 \\ - 5x = 16000 \\ x = - 3200$
