Question

6+ [15-(8: ax 7+7)] x 5 = 8: (1 x 4) + 3x3​

Answer 1

6+ [15-(8: ax 7+7)] x 5 = 8: (1 x 4) + 3x3​

6+ [15-(56:a+7)] x 5 = 8: 4 + 9

6+ [15-(56:a+7)] x 5 = 2 + 9

6+ [15-(56:a+7)] x 5 = 11

[15-(56:a+7)] x 5 = 5

15-(56:a+7)= 1

56:a+7=14

56:a=7

a=8

Answer 2

Explicație pas cu pas:

6+[15-(8:ax7+7)]x5=8:4+9

6+[15-(8:ax7+7)]×5=11

[15-(8:ax7+7)]x5=5

15-(8:ax7+7)=1

8:ax7+7=15-1

8:ax7+7=14

8:ax7=7

8:a=1

a=8:1

a=8
