I. RESOLVER LAS SIGUIENTES IDENTIDADES

1) -25X +157 -18 = -33X +25 -67

X=22.6

2) (2)(-4)(5) + (-2)(3)(8) + 16X = 145

X=14.5

3) ((15/4)(16/7)/(33/22)(12/21))X + 24 - (16/7) = 52 - (45/5)

X=6.1

4) ((29/7)(134) -45 + 29 = 15X - (34/6)

X=51.1

5) 256 - (425/25) + (156/4) = 36X

X=7.7

6) (-2)(-3)(-5)(4) + (-6)(-7)(4) - 41 = 67 -18X

X=10

7) (12/9) + (13/15) - (18/3) + 222X = 475 - (11/4)

X=-16
