Question

8546+127-96÷3+73×2-(62×a+24÷2)-5×11=689.

Answer 1

Explicație pas cu pas:

8546+127-(96÷3)+(73×2)-(62×a+24÷2)-(5×11)=689

8673 - 32 + 146 - (62×a + 12) - 55 = 689

8819 - 87 - (62×a + 12) = 689

8732 - (62×a + 12) = 689

62×a + 12 = 8732 - 689

62×a + 12 = 8043

62×a = 8043 - 12

62×a = 8031

a = 8031/62
