Question

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

Answer 1

$8x - x - 7 = 0$

$8x - x - 7 + 7 = 0 + 7$

$8x - x = 7$

$7x = 7$

$\frac{7x}{7} = \frac{7}{7}$

$x = 1$

$8 \times 1 - 1 - 7 = 0$

$8 - 1 - 7 = 0$

$8 - 8 = 0$

$0 = 0$

Answer 2

Explicación paso a paso:

$8x - x - 7 = 0 \\ 8x - x = 7 \\ 7x = 7 \\ x = 7 \div 7 \\ x = 1$

Comprobando

$8x - x - 7 = 0 \\ 8(1) - (1) - 7 = 0 \\ 8 - 1 - 7 = 0 \\ 7 - 7 = 0 \\ 0 = 0$
