ayuda con estas ecuaciones por fa, son para hoy D:
(si no sabes no respondas)

Answer 1

Explicación paso a paso:

#C

(24 -10 +2x) ( 24 -1 - x )

________ = ________

4 3

7 + x 23 - x

________ = _______6

2 3

21 +3x = 46 -2x

5x = 46 - 21

5x = 25

×=5

#D

x -5 +3 4x +2

______ = ______

6 9

3 ( x -2) = 2 ( 4x +2 )

3x -6 = 8x +4

-10 = 5x

x = -2

Answer 2

$3 - \frac{2(5-x)}{8} = 4 - \frac{-1-x}{6}$

mcm  = 24

72 - 6(5-x) = 96 - 4(- 1 - x)

72 - 30 + 6x = 96 + 4 + 4x

42 + 6x = 100 + 4x

6x - 4x = 100 - 42

2x = 58

x = 58/2

x = 29

$\frac{x-5}{6} + \frac{1}{2} = \frac{4x+2}{9}$

mcm = 18

3(x -5) + 9 = 4x + 2

3x - 15 + 9 = 4x + 2

3x - 6 = 4x + 2

-6  -2 = 4x + 3x

-8 = 7x

-8/7 = x
