tarea 4 algebra

1.- 73x
2.- x/15
3.- 16/x
4.- 22-x
5.- x+34
6.- 7x-5
7.- x/3
8.- (23/12)(15/7)-24x = 64-11x
(23/12) (15/7) =-24x= 64-11x
345/84=64-11x+24=64-13x
4.10-64=13x
-59.9=13x
x=-59.9/13=4.60
X=4.60
9.- 45-(28/5)+33/2=16x
45-5.6+16.5=55.9=16x
x= 55.9
10.- ((11/3)(45/7)/(26/9)(14/3))x+25-18=33
(495/21) / (364/27)=13365/7644x + (25/1)-(18/1)=33
13365/7644x = 33-25+18
13365/7644x = 26
1.74x=26
1.74/26= 14.94
x=14.94
11.- 625-34+(256/4)+42x=758-16/3
625-34+64+42x=758-5.33
387x=752.67
x=1.9

12.- ((4

28/6)(47/3))x+(-2)(-4)(3)-(-2)(-3)(4)(6)=16
(1316/18)x + 24-24(6)= 6
1316/18x + 0 = 6
x=6-1316//18-0
x=108-1316/18
x=-1208/18
X= -67.11
13.-((17/14)(16/2)/(55/4))+25/18=44-33
(272/8)(55/4)=1088/440+25/1-18/1=44-33x
1088/440+25-18-44=-33x
1088/440+-37=33x=1088+16280/440
=-15192/440
=-34.52
x=-34.52/33
x=-1.04
14.- (11/18)-23+2x=-17x+29-(13/21)
2x+17x=29-13/21-11/18+23
19x=52-234-231/378=19653/378
X=51.99/19
X=2.73
15.-1236-458+478-158x=457+(-2)(6)(7)(11)
1256-158x=457+-942
1256-158x=-467
1256+467=158x
1723=158x
X=1723/158
X=10.90
