[tex]9 \times 5 = 45 \\ 8 \times 4 = 32 \\ 42 \div 6 = 7 \\ 81 \div 9 = 9 \\ 296 - 165 = 131 \\ 436 - 112 = 324 \\ 103 + 323= 426[/tex]
[tex]x \times 5 = 45 \\ x = 45 \div 5 \\ x = 9[/tex]

[tex]81 \div x = 9 = > x = 9[/tex]
[tex]296 - x = 131 = > x = 165[/tex]
[tex]103 + x = 426 = > x = 426 - 103 = 323[/tex]
