7. x/3

II.RESOLVER LAS SIGUIENTES IDENTIDADES

8. (23/12)(15/7)-(1.91)(2.14)-24x=64-11x
(1.91)(2.14)-24x=64-11x
4.08-24x=64-11x
-24x+11x=64-4.08
-13x=59.92
x=59.92/-13
x=-4.60

9. 45-(28/5)+33/2=16x
45-5.6+16.5=16x
39.4+16.5=16x
55.9=16x
x=55.9/16
x=3.49

10. ((11/3)(45/7)/(26/9)(14/3)x+25-18=33
((3.6)(6.4)/(2.8)(4.6))x+25-18=33
(23.04)/(12.88)x+25-18=33
1.78x+25-18=33
1.78x=33-25+18
1.78x=26
x=26/1.78
x=14.60

11. 625-34+(256/4)+42x=758-16/3
591+64+42x=758-5.3
655+42x=752.7
42x=752.7-655
42x=97.7
x=97.7/42
x=2.32

12. ((28/6)(47/3))x+(-2)(-4)(3)-(-2)(-3)(4)(6)=16
(4.6)(15.6)x+24-14=16
71.76x=216-24+144
71.76x=136
x=136/71.76
x=1.89

13. ((17/4)(16/2)/(55/4))+25-18=44-33x
(4.25)(8)/(13.75)+25-18=44-33x
(34)/(13.75)+25-18=44-33x
2.47+25-18=44-33x
2.47+25-18-44=-33x
-34.53=-33x
x=-34.53/-33
x=1.04

14(11/18)-23+2x=-17x+29-(13/21)
0.61-23+2x=-17x+29-0.619
0.61+2x=-17x+28.38
2x+17x=28.38-0.61
19x=27.77
x=27.77/19
x=1.46

15. 1236-458+478-158x=457+(-2)(6)(7)(11)
1256-158x=457+(-924)
1256-158x=-467
-158x=-467-1256
-158x=-1723
x=-1723/-158
x=10.90
