Question

Tìm x:

8,75 × X +1,25× X=20

Answer 1

x . (8,75 + 1,25) = 20

X .10=20

X=20 : 10

X =2

Answer 2

\(8,75.x+1,25.x=20\)

\(x.\left(8,75+1,25\right)=20\)

\(\Leftrightarrow\)\(x.10=20\)

\(\Rightarrow\)\(x=20:10=2\)

Ai thấy đúng thì ủng hộ nha !!!

Answer 3

8, 75 x X + 1, 25 x X = 20

2x = 20 : (8, 75 + 1, 25)

x = 20 : 10

x = 2

Answer 4

(8,75+1,25)xX=20

10 x X=20

X        =20:10

X        =2

Answer 5

X sẽ bằng 2

Answer 6

 8,75x X + 1,25 x X = 20

(8,75+1,25)x X        =20

10x X                     =20

      X                     =20:10

      x                    = 2

Answer 7

8,75 x X + 1,25 x X = 20 

X x (8,75 + 1,25) = 20 

X x 10 = 20 

 X = 20 : 10 

X = 10

Answer 8

8.75*X+1.25*X=20

(8.75+1.25)*X=20

10*X=20

X=2

Answer 9

8,75 x X + 1,25 x X = 20

    X x (8,75 + 1,25) = 20 

                   X x 10 = 20

                           X = 20 : 10 

                           X = 2
