cuarta tarea

encontrar el valor de la x


1.- ((14/2)(15/7)) / ((256/14)(357/19)) +35x = 753951 + 456852 - 852963
(210/14) (91392/266) +35x=753957+456852-852963
55860/1279488+35x=357840
-1223628+35x=357840
-357840-1223628=-35x
-865738=35x
x=-865738/-35
x=24735




2.- 5/3 + 14/7 = 4x
77/21=4x
3.6=4x
x=3.6/4
x=0.9





3.- 127/4 + 456/4 - 123/4 = 16x + 64/4
508+1824/16-123/4=9328
9328-1968/64=7360/64
7360/64=16x+16
115=32x
x=115/32
x=3.5





4.- (2)(-3)(5) + 25X = (147/15)X - 248/43 - 223/105
30+25x=29.4x-5.7-2.1
5.7+2.1+30=29.4x-25x
37.8=4.4x
x=37.8/4.4
x=8.59






5.- (45/7)/(198/26) + 28X = 13 + (14/67)(222/111)
1170/1386-28x=13+3108/7437
0.8+28x=13+0.4
-13-0.4+0.8=-28x
-12.6=28x
xP=-12.6/-28
x=0.45






6.- 48/5 + (2/3)X = 1657 + 345
144+10/15=154/10
10.2x=2002
x=2002/-10.2
x=196.2






7.- (2)(-5)(-7)(-8)(9) + 257896 -1247 -5X = 951753 + 456
-5040+257896-12475x=952209
251609-5x=952209
-5x=952209-251609
-5x=700600
x=700600/5
x=140120






8.- 23/3 + (16/7)x = 23x -12
161+48/21=209/21
9.9x=23x-12
9.9x-23x=12
-13.1x=12
x=12/13.1
x=0.9





9.- 12x - 18 + (23/7) = 145/24 - 4x
12x-18+3.2=6.0-4x
-18+3.2=6.0-4x-12x
8.8=-16x
x=8.8/16
x=0.55=






10.- (6/7)(3/4) + 3x = 4 -(17/5)
18/28+3x=4-3.6
0.6+3x=4-3.6
3x=4.3+4-0.6
3x=7.7
x=3/7.7
x=0.389
