Question

X:(17+13) =75:25, 120:(x-8) =29+31 , (17-x) :3=78:17 , (24-x) *5=48-23 , x:4+78=89-10

Answer 1

Ответ:

1)90

2)10

3)55/17

4)19

5)4

Answer 2

(17+13)+=75:25 30 = 3 x = 3

120:(x-8)+=29+31 120/(x-8) = 60 x-8 = 2 x = 10

(17-x):3=78:17 17-x = 78*3 17-x = 234 x = -217

(24-x)*5=48-23 120-5x = 25 -5x = -95 x = 19

x:4+78=89-10 x/4 + 78 = 79 x/4 = 1 x = 4

Итак, значения переменной x равны 3, 10, -217, 19 и 4.
