Question

5x +x = 39 -3²

Answer 1

5x + x = 39 + 3²

5x + x = 39 + 9

5x + x = 48

4x       = 48

x         = 48 : 4

x         =    12 

Answer 2

5x + x = 39 - 3²

x . ( 5 + 1 ) = 39 - 9

x . 6 = 30

x = 30 : 6

x = 5

Answer 3

5x+x=39-3²

5x+x=39-9

5x+x=30

x.(5+1)=30

x.6=30

x=30:6

x=5

Vậy x=5

Answer 4

=> 5x+x=39-27

=> 6x=12

=> x=12:6

=> x=2

Answer 5

5x+×=39_9                                   

X(5+1)=30

××6=30

×=30÷6

x=5
