Question

7(x - 2) - 6x +
1 = 3 - 4x

X - 2/5 + X/4=5

​

Answer 1

Explicación paso a paso:

7(x - 2) - 6x + 1 = 3 - 4x

7x-14-6x+1 = 3-4x

7x-13-6x = 3-4x

7x-6x=3+13-4x

x = 16-4x

x+4x= 16

5x = 16

x= 16/5

$x - \frac{2}{5} + \frac{x}{4} = 5$

multiplicar por 20

$20 \times x - 20 \times \frac{2}{5} + 20 \times \frac{x}{4} = 20 \times 5$

$20x - 4 \times 2 + 5x = 100$

$20x - 8 + 5x = 100$

$25x - 8 = 100$

$25x = 100 + 8$

$25x = 108$

$x = \frac{108}{25}$
