TAREA 4 GRUPO:1-4 MATUTINO

ENCONTRAR EL VALOR DE x

1.- (5/3)+(4/3) = 2X
(1.6)+(1.3)=2x
2.9=2x
_2.9_=x
2
1.45=x
x=1.45

2.- (6/7)(3/9) + 3X = 4 - (17/5)
3x= 4 (17/5) - (6/7) (3/9)
3x = 4-12-(0.8)(0.3)
3x= -8-(0.8)(0.3)
3x=-8.8 (0.3)
3x=-2.64
x=_-2.64_
3

x=-0.88

3.- (23/3) + (16/9)X = 23X -12
(16/9)x -23x= -12-(23/3)
(1.7)x-23x= -12 -(23/3=
-213x=-12-(23/3)
-213x= -12-7.6
-213x= -19.6
x=_-19.6_
-213

x=0.09

4.- 12X - 18 + (23/7) = (145/2) -4X
12x+4x=(145/2) +18-(23/7)
16x=(72.5)+18-(3.2)
16x=54.5-(3.2)
16x=51.3
x=_51.3_
16

x=3.20


5.- ((14/2)(15/9) / (125/25)) = 17/3 + (13/4)X
(7)(3.75)/(5)= 5.6 + (13/4)x
26.25/5=5.6+(13/4)x
5.25=5.6+(13/4)x
5.25=5.6 + 3.25x
5.25=8.85x
_5.25_ =
8.85

0.59=x

x=0.59


6.- 22 -178 + 33/5 -16X = 147 + (248/16)
-16x - (248/6)x=147-22+178-35/5
-16x-(41.3)x=147-22+178-35/5
-57.3x=125+178-7
-57.3x=303-7
-57.3x=296
x=_296_
-57.3

x=-5.16


7.- (2)(-3)(5) + 25X = (147/15)X - 248/43 - 223/105
25x( 147/15)x=(2)(-3)(5)-248-223/105
25x -9.8x=-(2)(-3)(5)-248-223/105
25x-9.8x=-30-248-2.12
25x-9.8x=-278-2.12
15.2x=-280.12X=_-280.12_
15.2

X=18.42


8.- (45/7)/(198/26) + 28X = 13 + (14/67)(222/111)
28x=13+(14/67)(222/111)-(45/7)-(198/26)

28x= 13+(0.2)(2)-(6.4)/(7.6)
28x =13.2(2)-(6.4)//(7.6)
28x=26.4-(6.4)/(7.6)
28x=20/(1.16)
28x=17.2
X=_17.2_
28

X=0.61


9.- 48/5 + (2/3)X = 1657 + 345

(2/3)x= 1657+345-48/5
(0.6)x=2002-9.6
(0.6)x=1992.4
X=_1992.4_
0.6

X=3.32


10.- (2)(-5)(-7)(-8)(9) + 257896 -1247 -5X = 951753 + 456
