Resolver las siguientes ecuaciones:
1.- 3/7 + 2/5 -(16/8)x=-5.17
X= -3
3/7 + 2/5 -(16/8)-3
3/7 + 2/5=29/35 (16/8)(-3/1)=-48/8
29/35(-) -48/8=-1448/280=-5.17

2.- 15-17+33x-9x=118
X= 5
15-17+33(5)-9(5)
15-17=-2+165=163-45=118 33(5)=165 -9(5)=-45


3.- ((9/5)(5/8))x + (2/3)x +54=46.9
X= -4
((9/5)(5/8))-4+(2/3)-4+54
(9/5)(5/8)=(45/40)(-4/1)=-180/40(+)-8/3=-860/120=-7.1+54=46.9 (2/3)(-4/1)=-8/3



4.- (18/7)/((17/5)(8/9))x +19=21.3
X= 2
(18/7)/((17/5)(8/9))2+19
(17/5)(8/9)=(136/45)(2/1)=272/45(/)18/7=1904/810=2.3+19=21.3



5.- (22/16)-17/9+33x-67-6x=10.4
X = -2
(22/16)-17/9+33(-2)-67-6(-2)
22/16 - 17/9=-74/144 + 66/1=9430/144=65.4-67+12=10.4 33(-2)=-66 -6(-2)=12


6.- 23x-185x+215x-13+44=402
X= 7
23(7)-185(7)+215(7)-13+44
23(7)=161 -185(7)=-1295 +215(7)=1505
161-1295=1134+1505=371 -13+44=31
371+31=402

7.- 42/15 + 33/9 -28x =224.7
X= 8
42/15+33/9-28(8)
42/15+33/9=378/495=0.7+224=224.7 -28(8)=-224

8.- (25/4)(6/9) + 1/2-16x-89+46=-114.7
x= -5
(25/4)(6/9)+1/2-16(-5)-89+46
(25/4)(6/9)=150/36+1/2=300/36=8.3 -80-89 +46=-114.7 -16(-5)=80

9.- ((24/5)/(19/7))x +13x-157x+79=1281
X= 7
((24/5)/(19/7))7+13(7)-157(7)+79
(24/5)/(19/7)=(168/95)(7/1)=1176/95=12.3+91+1099+79=1281
13(7)=91 -157(7)=-1099


10.- ((156/37)/(456/89))x +23x-179=-179
X= 0

((156/37)/(456/89))0+23(0)-179
(156/37)(456/89)=(71136/3293)(0/1)=0/3293=0+0=0-179=-179
