ENCONTRAR EL VALOR DE x
1.- ((14/2)(15/7)) / ((256/14)(357/19)) +35x = 753951 + 456852 - 852963

(14/2)(15/7)=210/14
(256/14)(357/19)=91392/266
(210/14)/(91392/266)+35x=753951+45682-852963
(210/14)(91392/266)=55860/1279488
55860/1279488+35x=357840
-1223628+35x=357840
-357840-1223628=-35x
-35x=-865738
x=865738/-35 x=24735

2.- 5/3 + 14/7 = 4x

5/3+14/7=35+42/21=77/21=3.6
4x=3.6
x=3.6/4 x=0.9


3.- 127/4 + 456/4 - 123/4 = 16x + 64/4

127/4+456/4=508+1824/16=2332/16
2332/16-123/4=9328-1968/64=7360/64 64/4=16
7360/64=16x+16
7360/64=115
16x+16=32x
32x=115
x=115/32
x=3.5



4.- (2)(-3)(5) + 25X = (147/15)X - 248/43 - 223/105

-248/43=5.7 -223/105=-2.1
-30+25=29.4x-5.7-2.1
5.7+2.1+30=29.4x-25x
37.8=4.4x
x=37.8/44=8.5 x=8.5



5.- (45/7)/(198/26) + 28X = 13 + (14/67)(222/111)

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


6.- 48/5 + (2/3)X = 1657 + 345

48/5+2/3=144+10/15=154/15=10.2
1657+345=2002
x=2002/-10.2
x=-196.2


7.- (2)(-5)(-7)(-8)(9) + 257896 -1247 -5X = 951753 + 456

(2)(-5)(-7)(-8)(9)=-5040+257896-1247-5x=952209
-5040+257896=252856-1247=251609
251609-5x=952209
-5x=952209-251609
-5x=700600
x=700600/5
x=140120


8.- 23/3 + (16/7)x = 23x -12

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


9.- 12x - 18 + (23/7) = 145/24 - 4x

12x-18+3.2=6.04-4x
-18+3.2=6.04-4x-12x
16x=8.8
x=8.8/16
x=0.55



10.- (6/7)(3/4) + 3x = 4 -(17/5)
(6/7)(3/4)=18/28=0.6
0.6+3x=4-3.4
3x=3.4+4-0.6
3x=6.8
x=6.8/3
x=2.2
