Tìm x : biết

8x = 7,8 .x + 25

Answer 1

Answer 2

8x = 7,8.x+25

8x - 7,8x = 25

0,2x = 25

x = 25 : 0,2

x = 125

vậy x = 125

Answer 3

8x=7,8.x+25

8x-7,8x=25

x(8-7,8)=25

x.0,2=25

x=50

Answer 4

\(8x=7.8x+25\\ 8x-7.8x=25\\ 0.2x=25\\ x=25:0.2\\ x=125\)

Vậy \(x=125\)

Answer 5

=> 8x -7,8x=25

=>0,2x=25

=>x=25:0,2

=>x=125

Answer 6

x= 125 đấy
