alguien que lo pueda resolver paso a paso​

Answer 1

Hola!!!

Ecuación de primer grado

$2(7 - x) + 7x = 8 - 5(x - 1) + </u><u>8</u><u> </u><u> </u><u>*</u><u> + 4$

Procedimiento :

$2(7 - x) + 7x = 8 - 5(x - 1) + </strong><strong>8</strong><strong> </strong><strong> </strong><strong>*</strong><strong> + 4$

$14 - 2x + 7x = 8 - 5x + 5 + </strong><strong>8</strong><strong> </strong><strong> </strong><strong>*</strong><strong> </strong><strong> + 4$

$- 2x + 7x + 5x </strong><strong> =</strong><strong> </strong><strong>32</strong><strong> </strong><strong>+</strong><strong> </strong><strong>5</strong><strong> </strong><strong>+</strong><strong>8</strong><strong> </strong><strong>-</strong><strong> </strong><strong>14</strong><strong>$

$10x = </strong><strong>31</strong><strong>$

$x = \frac{</strong><strong>31</strong><strong>}{10}$

La respuesta es x = 31/10, no se puede simplificar
