Respuesta:

[tex]8 \times - 7 + \times = 5 \times +21 \\ 9 \times - 7 = 5 \times + 21 \\ 9 \times - 5 \times = 21 + 7 \\ 4 \times = 28 \\ \times = 7 \\ \\ [/tex]

[tex]7 \times - 2 = 12 \\ 7 \times = 14 \\ \times = 2[/tex]

[tex] \times \div 3 = 8 \\ \times = 24[/tex]

[tex] \times \div 2 + 1 = 15 \\ \times + 1 = 30 \\ \times = 29[/tex]

[tex] { \times }^{2} - 1 = 8 \\ { \times }^{2} = 9 \\ \times = 3[/tex]
