Question

$\frac{8x - 1}{2} - 2x = 3$
​

Answer 1

Resposta:

$\frac{8x - 1}{2} - 2x = 3$

$\frac{8x - 1}{2} - \frac{4x}{2} = \frac{6}{2}$

$8x - 1 - 4x = 6$

$8x - 4x = 6 + 1$

$4x = 7$

$x = \frac{7}{4}$

Answer 2

$\frac{8x - 1}{2} - 2x = 3$

Multiplicar por 2

$2( \frac{8x - 1}{2} - 2x) = 2 \times 3$

$8x - 1 - 4x = 6$

$4x - 1 = 6$

$4x = 6 + 1$

$4x = 7$

$x = \frac{7}{4} = 1.75$
