Question

(6. x - 39).28 = 5628

(9. x + 2). 3 =60

 

Answer 1

( 6x -39 ) .28 = 5628 

6x-39 = 5628 : 28

6x-39 = 201

6x = 201+39

6x = 162

x = 27

Vậy x = 27

(9x +2 ).3 =60

9x+2 =60:3

9x+2 = 20

9x =20-2

9x = 18

x = 2

Vậy x =2

Answer 2

(9x +2 ).3 =60
9x+2 =60:3
9x+2 = 20
9x =20-2
9x = 18
x = 2
