Question

d. 101 x [101 - (101 - 102: x)] = 202
369 - [(x + 112): 5 + 113] = 434
f. 104: [(x - 3x 8)x2:8]=13​

Answer 1

Răspuns:

101 x [101 - (101 - 102: x)] = 202

[101 - (101 - 102: x)] = 202:101

101-(101-102:x)=2

(101-102:x)=101-2

101-102:x=99

102:x=101-99

102:x=2

x=102:2

x=51

369 - [(x + 112): 5 + 113] = 434

[(x+112):5+113]=369-434

(x+112):5+113=-65

(x+112):5=-65-113

(x+112):5=-178

(x+112)=-178x5

x+112=-890

x=-890-112

x= -1002

104: [(x - 3x 8)x2:8]=13

[(x-24)X2:8]=104:13

(x-24)X2:8=8

(x-24)X2=8x8

(x-24)X2=64

(x-24)=64:2

x-24=32

x=32+24

x=56
