Answer 1

Ответ:

Пошаговое объяснение:

48 + y : 6 = 95

y : 6 = 95 - 48

y : 6 = 47

y = 47 * 6

y = 282

720 - x = 90 * 2

720 - x = 180

x = 720 - 180

x = 540

80 - (7 + x) = 53

7 + x = 80 - 53

7 + x = 27

x = 27 - 7

x = 20

(x - 12 ) * 8 = 56

x - 12 = 56 : 8

x - 12 = 7

x = 7 + 12

x = 19

Answer 2

Решение:

$48 + y \div 6 = 95 \\ y \div 6 = 95 - 48 \\ y \div 6 = 47 \\ y = 47 \times 6 \\ y = 282$

=====================================

$720 - x = 90 \times 2 \\ 720 - x = 180 \\ x = 720 - 180 \\ x = 540$

=====================================

$80 - (7 + x) = 53 \\ 7 + x = 80 - 53 \\ 7 + x = 27 \\ x = 27 - 7 \\ x = 20$

======================================

$(x - 12) \times 8 = 56 \\ x - 12 = 56 \div 8 \\ x - 12 = 7 \\ x = 7 + 12 \\ x = 19$
