Answer 1

Respuesta:

Ecuación

[tex]42 - 4p = - 39 \\ - 4p = - 39 - 42 \\ - 4p = - 81→ \times - 1 \\ 4p = 81 \\ \boxed{p = \frac{81}{4}} [/tex]

Comprobación

[tex]42 - 4p = - 39 \\ 42 - \boxed{4 \times \frac{81}{4}} = - 39[/tex]

[tex]4 \times \frac{81}{4} = \frac{4}{1} \times \frac{81}{4} = \frac{4 \times 81}{1 \times 4} = \frac{324}{4} = 81[/tex]

[tex]42 - 81 = - 39 \\ \boxed{ - 39 = - 39}✔[/tex]

Respuesta:

[tex] \boxed{ \color{green}{p = \frac{81}{4}}}[/tex]
