Question

1. tìm x

(x+1)+(x+4)+(x+7)+(x+10)=62

Answer 1

(x+1)+(x+4)+(x+7)+(x+10)=62

( x + x + x + x ) + ( 1 + 4 + 7 + 10 ) = 62

4x + 22 = 62

4x = 62 - 22

4x = 40

x = 40 : 4

x = 10

Answer 2

(x + 1) + (x + 4) + (x + 7) + (x + 10) = 62

x + 1 + x + 4 + x + 7 + x + 10 = 62

4x + 22 = 62

4x = 40

=> x = 40 / 10 = 4

Answer 3

x= 4 nha bn

k mk nha

mk k lại cho!

Answer 4

4x+(1+4+7+10)=62

4x+     22         =62

4x                   =62-22

4x                   =40

 x                    =40:4

x                     =10

Vậy x=10
