Question

3+{4×[2+(6+a):3]-17}×7=24​

Answer 1

Răspuns:

a = 3

Explicație pas cu pas:

3+{4×[2+(6+a):3]-17}×7 = 24

{4×[2+(6+a):3]-17}×7 = 24-3 = 21

{4×[2+(6+a):3]-17} = 21:7 = 3

4×[2+(6+a):3]-17 = 3

4×[2+(6+a):3] = 3+17 = 20

[2+(6+a):3] = 20:4= 5

2+(6+a):3 = 5

(6+a) : 3 = 5-2 = 3

6+a = 3×3 = 9

a = 9-6 = 3

a = 3
