Ответ:
1)
[tex]x = 3[/tex]
2)
[tex]12[/tex]
3)
[tex]x = 16 - 8[/tex]
[tex]x = 8[/tex]
Объяснение:
[tex]2x + 3 = 9 \\ 2x = 9 - 3[/tex]
[tex]2x = 6 \\ x = 6 \div 2[/tex]
[tex]4 \times (5 - 2) = 4 \times 3 = 12[/tex]
[tex]8 + x = 16 \\ x = 16 - 8[/tex]
2х + 3 = 9
2х = 9 - 3
2х = 6
х = 6 : 2
х = 3
4 * (5 - 2) = 4 * 3 = 12
8 + х = 16
х = 16 - 8
х = 8

Объяснение:
2х + 3 = 9
2х = 9 - 3
2х = 6
х = 6 : 2
х = 3
4 * (5 - 2) = 4 * 3 = 12
8 + х = 16
х = 16 - 8
х = 8
