Question

46+y:5=85
49+(136-x*8):4=81

Answer 1

Пошаговое объяснение:

$46 + y \div 5 = 85 \\ 46 + \frac{y}{5} = 8 \\ 230 + \frac{y}{5} = 425 \\ \frac{y}{5}= 425 - 230 \\ \frac{y}{5} = 195$

у=195*5;

у=975.

$49 + (136 - x \times 8) \div 4 = 81 \\ 49 + \frac{136}{4} - \frac{8x}{4} = 81 \\ 49 + 34 - 2x = 81 \\ - 2x = 81 - 49 - 34 \\ - 2x = - 2 \\ x = 1$
