tercer tarea del 1-4 matutino

1-r=12x-(5/8)-23=11
12x=+(0.625)+23-11
12x=12.625
x=12.625/12
x=1.0520833

2-r=((6/6)(4/9)+23x-(7/5)=(9/2)
23x=-4.5+1.4+24/54
23x=-4.5+1.4+0.45
23x=-2.65
x=-2.65/23
x=-0.1152173

3-r=((18/6)/(24/17))x+25-18=65
((18/6)/(24/17))x=-65+18-25
(3)/(1.14117647)x=-65+18-25
2.1161826x=-72
x=-72/2.1161826
x=-34.023528

4-r=(-2)(5)(3)+(-3)(-6)(5)+(172)x+14=19
1/2x=-19-14-(-3)(-6)(5)-(-2)(5)(3)
1/2x=-19-14-90--30
1/2x=-153/0.5
x=-306

5-r=((19/13)(27/6)/(35/4)+22=73x
73x=-22-(19/13)/(35/4)
73x=-22-(6.34)/(8.75)
73x=22-0.7245714
73x=22.724571
x=22.724571/73
x=-7.574857

6-r=184x-235-6/5=212x-66
(184)(212)x=+66+6/5+235
(184)(212)x=+66+1.2+235
(184)(212)x=302.2
39008x=302.2
x=302.2/39008
x=0.0077471

7-r=(44/16)(2)-15x+33=45x-79+(12/16)
(15)(45)x=-(12/6)+79-33(2)(44/16)
(15)(45)x=-2+79-33(2)2.75
(15)(45)x=242
x=675/242
x=2.7892561

8-r=x+18

9-r=(x)(5)-4

10-r=(x/4)(17)

11-r=x/3

12-r=x/7

13-r=x/4+9

14-r=36 x
