Question

 X + 2X + 3X + 4X = 150 ai giải hộ e vs ạ

Answer 1

X(1+2+3+4)=150

10X=150

X=15

Answer 2

 X x ( 1+2+3+4) = 150

 X x 10 = 150

       X = 150 : 10

       X= 15

Vậy X=15

Answer 3

X + 2X + 3X + 4X = 150

          (1+2+3+4)x = 150 

                     10x  = 150

                         x = 15

Answer 4

x+2x+3x+4x=150

1x+2x+3x+4x=150

X x (1+2+3+4) =150

X x 10 =150

x =15

Answer 5

x + 2x + 3x + 4x = 150

x . (1 + 2 + 3 + 4) = 150

x . 10 = 150

x = 150 : 10

x = 15

Answer 6

x=15
