Question

1: 6 + [3 x 76 - 23 x 3 -(88 – 5×x): 3] : 3 = 52. Dau coroană !!​

Answer 1

Răspuns:

6 + [3 x 76 - 23 x 3 -(88 – 5×x): 3] : 3 = 52.

[228 - 69 -(88 – 5×x): 3] : 3=52-6

[159-(88-5xx):3]:3=46

[159-(88-5xX):3]=46x3

159-(88-5xX):3=138

(88-5xX):3=159-138

(88-5xX):3=21

(88-5xX)=21x3

88-5xX=63

5xX=88-63

5xX=25

x=25:5

x=5
