Question

B) 2(x + 1) + 3(x - 2) = 4(2 - x) + 6
c) 7x/6 - 5/3= 3x/4
d) x+6/7- x+7/8 = x+8/9

Answer 1

Explicación paso a paso:

B.2(x+1)+3(x-2)=4(2-x)+6

2x+2+3x-6=8-4x+6

2x+3x+4x=8+6-2+6

9x=18

x=18/9

x=2

C. 7x/6-5/3=3x/4. Su mcm es 12

14x-20=9x

14x-9x=20

5x=20

x=20/5

x=4

D. x+6/7-x+7/8=x+8/9. Su mcm es 504

72x+6-63x+7=56x+8

72x-63x-56x=8-6

- 47x=2

x=2/-47

Answer 2

Respuesta:

$\frac{7x}{6} - \frac{5}{3} = \frac{3x}{4} = \\ 14x - 20 = 9x = \\ - 20 = 9x - 14x = \\ - 20 = - 5x = \\ \frac{ - 20}{ - 5} = x \\ \frac{20}{5} = x \\ 4 = x \\ x = 4$

$2(x + 1) + 3(x - 2) = 4(2 - x) + 6 = \\ 2x + 2 + 3x - 6 = 8 - 4x + 6 = \\ 5x - 4 = 8 - 4x + 6 = \\ 5x - 4 = - 4x + 14 = \\ 5x = - 4x + 14 + 4 = \\ 5x = - 4x + 18 = \\ 5x + 4x = 18 = \\ 9x = 18 \\ x = \frac{18}{9} \\ x = 2$

$x + \frac{6}{7} - x + \frac{7}{8} = x + \frac{8}{9} = \\ \frac{6}{7} - x + \frac{7}{8} = \frac{8}{9} \\ \frac{97}{56} - x = \frac{8}{9} = \\ - x = \frac{8}{9} - \frac{97}{56} = \\ - x = - \frac{425}{504} = \\ x = \frac{425}{504}$
