Answer 1

X x 2 + X x 3 = 40

X x ( 2 + 3 ) = 40

X x 5 = 40

X = 40 : 5

X = 8

Answer 2

x*2+x*3=40

=>x*(2+3)=40

=>x*5=40

=>x=40:5

=>x=8

Vậy x=8

Answer 3

X x 2 + X x 3 = 40

X x(2+3)=40

X x 5 = 40

  X = 40: 5

X = 8

Answer 4

 X x ( 3 + 2 ) = 40

 X x 5 = 40

    X = 40 : 5 = 8 

Answer 5

X x 2 + X x 3 = 40

X x ( 2 + 3 )  = 40 

X x 5            = 40
