Question

8x-x-7 = 0 has su procedimiento y comprobante​

Answer 1

[tex]8x - x - 7 = 0[/tex]

[tex]8x - x - 7 + 7 = 0 + 7[/tex]

[tex]8x - x = 7[/tex]

[tex]7x = 7[/tex]

[tex] \frac{7x}{7} = \frac{7}{7} [/tex]

[tex]x = 1[/tex]

[tex]8 \times 1 - 1 - 7 = 0[/tex]

[tex]8 - 1 - 7 = 0[/tex]

[tex]8 - 8 = 0[/tex]

[tex]0 = 0[/tex]

Answer 2

Explicación paso a paso:

[tex]8x - x - 7 = 0 \\ 8x - x = 7 \\ 7x = 7 \\ x = 7 \div 7 \\ x = 1[/tex]

Comprobando

[tex]8x - x - 7 = 0 \\ 8(1) - (1) - 7 = 0 \\ 8 - 1 - 7 = 0 \\ 7 - 7 = 0 \\ 0 = 0[/tex]
