Răspuns:

c) x : 12 = 24

x = 24 * 12

x = 288

d) 144 : x = 6

x = 144 : 6

x = 24

e) 100 - (5 + x : 2) : 10 - 35 = 65

100 - (5 + x : 2) : 10 = 65 + 35

100 - (5 + x : 2) : 10 = 100

(5 + x : 2) : 10 = 100 - 100

(5 + x : 2) : 10 = 0

5 + x : 2 = 0 * 10

5 + x : 2 = 0

x : 2 = 5 - 0

x : 2 = 5

x = 5 * 2

x = 10
