Question

X + 2 x X + 3 x X + 4 x X = 50

Answer 1

X + 2 x X + 3 x X + 4 x X = 50

X x ( 1+2+3+4) =50

X x 10 =50

X =50 : 10

X =5

Answer 2

X+2×x+3×x+4×x=50 <=>x×(1+2+3+4)=50 <=>X×10=50 <=>X=50:10 <=>X=5 HỌC TỐT

Answer 3

X + 2 x X + 3 x X+ 4 x X = 50 

X x (1+ 2 + 3 + 4 )    = 50 

X x 10 = 50 

X = 50 : 10 

X = 5 

Answer 4

X + 2 x X + 3 x X + 4 x X = 50

X x ( 1 + 2 + 3 + 4 ) = 50

X x 10 = 50

X = 50 : 10

X = 5

Answer 5

X + 2 x X + 3 x X + 4 x X = 50 

= X + 2 x X + 3 x X + 4 x X + 1= 50 

= X x ( 2 + 3 + 4 + 1 ) = 50

= X x 10 = 50

   X = 50 : 10

   X = 5

Answer 6

\(x+2\times x+3\times x+4\times x=50\)

\(\Leftrightarrow x\times\left(1+2+3+4\right)=50\)

\(\Leftrightarrow x\times10=50\)

\(\Leftrightarrow x=50\div10\)

\(\Leftrightarrow x=5\)

Vậy x = 5
