Question

Tìm x:

4x:17=0;

7x-8=713;

8(x-3)=0

Answer 1

a/ x=0

b/ x=705/7

c/ x=-3

Answer 2

0

.4x : 17 = 0 

<=> 4x = 17

<=> x = 17/4 = 4,25

7x - 8 = 713

<=> 7x = 713 + 8

<=> x = 103

8 ( x - 3 ) = 0

<=> 8x - 24 = 0

<=> 8x = 24

<=> x = 4

Answer 3

4x:17=0                                                  7x-8=713                                                   8(x-3)=0

4x=0.17=0                                              7x=713+8=721                                             x-3=0:8=0

x=0:4=0                                                  x=721:7=103                                               x=0+3=3

Vậy x=0                                                 Vậy x=103                                                 Vậy x=3
