Question

Решить уравнение!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

Объяснение:

x+(2/3 × 21/50x)=340

x+(2×7/50x)=340

x+(7/25x)=340

x+7/25x=340

32/25x=340

x=2125/8

Answer 2

Объяснение:

$x = 265 \frac{5}{8}$

$x + ( \frac{2}{3} \times 0.43x) = 340 \\ x + ( \frac{2}{3} \times \frac{21}{50} x) = 340 \\ x + \frac{7}{25} x = 340 \\ 1 \frac{7}{21} x = 340 \\ x = 340 \div \frac{32}{25} \\ x = 340 \times \frac{25}{32} \\ x = 265 \frac{5}{8}$
