8x -75 = 5x + 21 

Answer 1

8x-75=5x+21

=>  8x-5x=21+75

=>    3x   =  96

=>     x    =  32

Answer 2

\(\Leftrightarrow8x-5x=21+75.\)

\(\Leftrightarrow3x=96\)

=> x= 32

Answer 3

8x-75=5x+21

8x-5x= 75+21

x.(8-5)= 96

x.3= 96

x= 96:3

x= 32

Vậy x= 32

Answer 4

8x - 75 = 5x + 21

8x - 5x = 75 + 21

   3x  = 96

    x = 96 : 3 = 32

Answer 5

8x - 75 = 5x + 21

=> 8x - 5x = 21 + 75

=> 3x = 96

=> x = 96 : 3

=> x = 32

Vậy x = 32
