Question

rozwiaz rownanie : a) x+7 1/2 = 3,2 b) 12,5 - x = 48 1/4 c) 13 2/3 + x= -5 1/6 d) x- 25 1/5 = -4,4 e) -7 5/6 + x=8 1.3 f) -12 4/5x= 1,6 g) -1,2x =- 1/2 h) 5 5/8 x = 18 i) 7/9 x = -16 1/3



pomocy ! :)))

Answer 1

a) x+7 1/2 = 3,2                                            e) -7 5/6 + x=8 1.3                i) 7/9 x = -16 1/3

x=3,2-7,5                                                        x=8 1/3  +7 5/6                         x=-16 1/3 / 7/9

x=-4,3                                                             x=16 1/6                                    x=21

b) 12,5 - x = 48 1/4                                      f) -12 4/5x= 1,6

-x=48 1/4-12,5                                              x=1,6/12.8

-x=35,75                                                        x=0,125

x=-35,75                                                       g) -1,2x =- 1/2

c) 13 2/3 + x= -5 1/6                                     x=1,5/-0,5

x=-5 1/6 -13 2/3                                            x=-3

x=-18 5/6                                                     h) 5 5/8 x = 18

d) x- 25 1/5 = -4,4                                        x=18/5 5/8

x=-4.4 +25 1/5                                             x=3,2

x=20,8
