respuestas de la segunda tarea del grupo 1.6

Resolver las siguientes ecuaciones:

1.- 3/7 + 2/5 -(16/8)x= x=2= -724/140= 5.17
X= -3
3/7+ 2/5= 14+15/35= 29/35
16/8 (-3/1)= -48/8
29/35-48/8= 1680-232/280=-1448/280= -724/140

2.- 15-17+33x-9x= x=5 = 118
X= 5
15-17+33(5)-9(5)=
15-17+165-45=118

3.- ((9/5)(5/8))x + (2/3)x +54= x=-4=864/30= 28.3
X= -4
(9/5)(5/8)= 45/40(-4/1)=-180/40
2/3(50/1)=100/3+-180/40= -540+4000/140=
3460/120= 865/30= 28.3

4.- (18/7)/((17/5)(8/9))x +19= x=2=2589/119= 21.75
X= 2
(18/7)(17/5)= 90/119
(21/1)+(90/119)= 2499+90/119= 2589/119= 21.75

5.- (22/16)-17/9+33x-67-6x= x=-2=10403/72= 144.48
X = -2
22/16-17/9= 272-198/144= 74/144
33(-2)-67-6(-2)
74/144-66-67-12=-145
74/144+-145/1= -20880+74/144=
-20806/144=10403/72
6.- 23x-185x+215x-13+44= x=7= 80
X= 7
-23(7)-185(7)+215(7)-13+44
-161-1295+1505-13+44
-161-1295-13=1469
1505+44= 1549
1549-1469= 80

7.- 42/15 + 33/9 -28x = x=5= 175/27= 6.48
X= 8
42/15+33/9= 495+378/135=
875/135=175/27= 6.48

8.- (25/4)(6/9) + 1/2-16x-89+46=
x= -5
9.- ((24/5)/(19/7))x +13x-157x+79=
X= 7
10.- ((156/37)/(456/89))x +23x-179=
X= 0
