CUARTA TAREA 1ª4 ALGEBRA

maestro ya se que dijo k ya no era nesesario pero aki esta



ENCONTRAR EL VALOR DE x

1.- (5/3)+(4/3) = 2X
(9/3)=2x
(9/3)/(2/1)=x
9/6=x
1.5=x

2.- (6/7)(3/9) + 3X = 4 - (17/5)
18/63+3x=4-(17/5)
18/63+3x=4-3.4
0.2857142+3x=4-0.285
3x=4-3.685
3x=0.315
x=0.315/33
x=0.105

3.- (23/3) + (16/9)X = 23X -12
7.67+1.78x=23x-12
1.78x=23x-12-7.67
1.78x=23x-19.67
1.78x=-23x=-19.67
-21..22x=-19.67
x=19.67/21.22
x=0.9269557

4.- 12X - 18 + (23/7) = (145/2) -4X
12x-18+3.28=72.5-4x
12x+4x=-72.5-3.28+18
18x=-57.75
X=-57.78/18
X=3.21


5.- ((14/2)(15/9) / (125/25)) = 17/3 + (13/4)X
((7)(1.67)/5)=17/3++(1314)x
(11.69/5)=17/3+(1314)x
2.338=5.67+1314x
2.338-5.67=1314x
-3.332=1314
-3.332/1313=x-0.0025357

6.- 22 -178 + 33/5 -16X = 147 + (248/16)X
22-178+6.6-16x=147+(1.55x)
-178+6.6-16x=147+15.5x-22
-16x=147+15.5x-22++178-6.6
-16x-15.5x=147-22+178-6.6
-31.5x=296.4
x=296.4/31.55
x=-9.4095238

7.- (2)(-3)(5) + 25X = (147/15)X - 248/43 - 223/105
-30+25x=9.8x-5.767-2.123
25x-9.8x=30-5.767-2.123
15.2x=30-7.890
15.2x=22.111
x=22.11/15.2
x=1.454605263

8.- (45/7)/(198/26) + 28X = 13 + (14/67)(222/111)
6.428571429/7.615384615+28x=13+(0.208955223)(2)=0.4490026649
48/5+(2/3)x=1657+345
9.6+0.67x=1657+345-9.6
0.67x=1657+345-9.6
0.67x=9962/5
x=199240/0.67
x2.973731343

9.- 48/5 + (2/3)X = 1657 + 345
48/5+(2/3)x=2002
2/3x=2002-48/5
2/3x=9962/5
x=(9962/5)/2/3
x=14943/5
x=2.9886
