CUARTA TAREA 1ª4 ALGEBRA

ENCONTRAR EL VALOR DE x


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

2.- (6/7)(3/9) + 3X = 4 - (17/5)
118/63+3x=4-(17/5)
0.285+3x=4-3.4
3x=0.6-0.285
3x=0.315
x=0.315/3

16x=50.285/16
x=3.1428125

5.- ((14/2)(15/9) / (125/25)) = 17/3 + (13/4)X
(210/18)/(125/25)=17/3+(3/4)
5250/2250=17/3+(3/4)x
2.34=17/3+(3/4)x
2.34=77/12x
2.34=6.416x
2.34/6.416=x
0.364=x

6.- 22 -178 + 33/5 -16X = 147 + (248/16)X
-156+6.6-16x=147+(248/16)x
-149.4-16x=147+15.5
-147-149.4-16x=15.5x
-296.4-16x=15.5x
-296.4-=16x+15.5x
-296.4=31.5x
-296.4/315=x
x-0.940952381

7.- (2)(-3)(5) + 25X = (147/15)X - 248/43 - 223/105
-30+25x=9.8x-16451/4515
-30+25x=9.8x-3.643
3.643-30+25x=9.8x
-26.357+25x=9.8x
-26.357=9.8x-25x
-26.357=-15.2x
-26.357/15.2=x
-1.734013158=x

8.- (45/7)/(198/26) + 28X = 13 + (14/67)(222/111)
1170/1386+28x=13+3108/7437
0.844+28x=13+0.417
0.844+28x=13.417
28x=13.417-0.844
28x=12.573
x=12.573/28
x=0.449035714

9.- 48/5 + (2/3)X = 1657 + 345
9.6+(2/3)x=2002
2/3x=2002-9.6
2/3x=1992.4
0.67x=1992.4
x=1992.4/0.67
x=2973.731343

10.- (2)(-5)(-7)(-8)(9) + 257896 -1247 -5X = 951753 + 456
-5040+257896-1247-5x=951753+456
