Answer 1

Respuesta

Soluciónes:

• A)    4x+32 = 0
• B)    5y-5 = 0
• C)    28x-168 = 0

Explicación paso a paso:

A) $\frac{x+8}{2} = \frac{x-4}{6}+2$

$\frac{x+8}{2} = \frac{x-4+12}{6}$

$\frac{x+8}{2} = \frac{x+8}{6}$

$6(x+8) = 2(x+8)$

$6x+48 = 2x+16$

$6x-2x+48-16 = 0$

$4x+32 = 0$

--------------------------------------------------------------------------------

B)  $3(y-5)-(8+2y) = 4(y-7)+2y$

$3y-15-8-2y = 4y-28+2y = 0$

$3y-2y-4y-15-8+28-2y = 0$

$-5y+5 = 0$

$5y-5 = 0$

----------------------------------------------------------------------------------

C) $\frac{x-2}{2}+\frac{1}{7} = \frac{5x}{14}$

$\frac{7(x-2)}{7(2)} +\frac{2*1}{7*2} = \frac{5x}{14}$

$\frac{7x-14}{14}+\frac{2}{14} = \frac{5x}{14}$

$\frac{7x-14+2}{14} = \frac{5x}{14}$

$\frac{7x-12}{14} = \frac{5x}{14}$

$14(7x-12) = 14(5x)$

$98x-168 = 70x$

$98x-70x-168 = 0$

$28x-168 = 0$
