Question

5 + 2∙[3 – 2∙(x – 3)]:2 = 37
Dau coroana ​

Answer 1

Răspuns:

5+2[3-2(x-3)]:3=37

5+2(3-2x-6):3=37

5+(6-4x-12):3=37

5+2-4/3x-4=37

3-4/3x=37

9-4x=111

-4x=111-9

-4x=102

-x=102/4

Answer 2

5 + 2∙[3 – 2∙(x – 3)]:2 = 37

5 + 2∙[3 – 2∙(x – 3)]=37∙2

5 + 2∙[3 – 2∙(x – 3)]=74

2∙[3 – 2∙(x – 3)]=74-5

2∙[3 – 2∙(x – 3)]=69

2∙(3-2∙x)=69+3

2∙(3-2∙x)=72

2∙3-2∙x=72

6-2∙x=72

2∙x=72-6

2∙x=66

x=66:2

x=33
