Question

Помогите решить уравнения ​

Answer 1

1.

$(y + 383) - 479 = 382 \\ y + 382 = 382 + 479 \\ y + 382 = 861 \\ y = 861 - 383 \\ y = 478$

2.

$32 \: 015 - x = 17 \: 609 \\ x = 32 \: 015 - 17 \: 609 \\ x = 14 \: 406$

3.

$18 \times (20 + x) = 70 \\ 20 + x = 720 \div 18 \\ 20 + x = 40 \\ x = 40 - 20 \\ x = 20$

4.

$(2 \: 505 - p) - 750 = 1 \: 005 \\ 2 \: 505 - p = 1 \: 005 + 750 \\ 2 \: 505 - p = 1 \: 755 \\ p = 2 \: 505 - 1 \: 755 \\ p = 750$

5.

$1 \: 000 - b = 791 \\ b = 1 \: 000 - 791 \\ b = 209$

6.

$x + 419 = 839 \\ x = 839 - 419 \\ x = 420$
