Частина 2. Номер 248

Розв’яжи рівняння.

8 + x = 32
x = 32 – 8
x = 24
8 + 24 = 32
32 = 32

8 • x = 2
x = 32 : 8
x = 4
8 • 4 = 32
32 = 32

70 – x = 56
x = 70 – 56
x = 14
70 – 14 = 56
56 = 56

7 • x = 56
x = 56 : 7
x = 8
7 • 8 = 56
56 = 56

x – 6 = 48
x = 48 + 6
x = 54
54 – 6 = 48
48 = 48

x • 6 = 48
x = 48 : 6
x = 8
8 • 6 = 48
48 = 48

19 + x = 27
x = 27 – 19
x = 8
19 + 8 = 27
27 = 27

9 • x = 27
x = 27 : 9
x = 3
9 • 3 = 27
27 = 27
