Tersera tarea

I. Resolver Los siguientes ejercicios

1) 12x -(5/8) -23 = 11
12x= 11 + 23 + (5/8)
12x= 11 + 23 + 0.63
12x= 34.63
x= 34.63 / 12
x= 2.89

2) ((6/6)(4/9)) + 23X - (7/5) = (9/2)
(24/54) + 23x - (7/5)= (9/2)
0.44 + 23x - 1.4= 4.5
23x= 4.5 + 1.4 - 0.44
23x= 5.46
x= 5.46/23
x= 0.24

3) ((18/6)/(24/17))x + 25 -18 = 65
(306/102)x + 25 - 18= 65
2.96x + 25 - 18= 65
2.96x= 6 + 18 - 25
2.96x= 58
x= 58 / 2.96
x= 19.56

4) (-2)(5)(3) + (-3)(-6)(5) +(1/2)x +4 = 19
-30 + 90 + 0.5x + 4= 19
0.5x= 19 - 4 - 90 - 30
0.5x= -105
x= -105 / 0.5
x= -210


5) ((19/13)(27/6)/(/35/4))+ 22 = 73x
(454/312) / (45/4) + 32= 83x
0.46 / 7.6 + 32= 83x
-19.28= 83x
-198.567 / 83= x
x= -134.89

6) 384x -458.35 -6/45 = 12312x -16
384x - 212= 66 + 6/5 + 235
384x - 212= 66 + 1.2 + 235
-28x= 12.2
x= 12.2 / -28
x= 1079

7) (44/16)(2) - 15x +33 = 45x -79 + (12/6)
2.75 (2) - 15x + 33= 45x - 79 + 0.75
15 + 45x= 0.75 - 79 + 33 - 2 / (2.75)
60x= -17.18
x= 17.18 / 60
x= -0.29


8)la suma de un numero y 18=x+18

9)un numero multiplicado por si disminuido en 4=x(5)-4

10)la cuarta parte de un numero multiplicado por 17=(x/4)(17)

11)un tercio de un numero=x/3

12)un numeroentre7=x/7

13)la cuarta parte de un numero aanido a 9=(x/4)+9

14)la diferencia de 36 y un numero=36-x
