Question

Tìm X biết :

X+2*x+3*x+4*x=100 ai giải giúp e vs toán lớp 5

Answer 1

\(x+2x+3x+4x=100\)

\(x\left(1+2+3+4\right)=100\)

\(x\times10=100\)

\(x=100\div10\)

\(x=10\)

Answer 2

x*(1+2+3+4) = 100

x*10 = 100

x = 10

Answer 3

x + 2*x + 3*x + 4*x = 100

x * ( 2 + 3 + 4 + 1) = 100

x * 10 = 100

x        = 100 : 10

x         = 10

Answer 4

x+2.x+3.x+4.x=100

x.(1+2+3+4)=100

x.10=100

x    =100:10

x    =10

Answer 5

x+2x+3x+4x=100

x(2+3+4+1)=100

10x=100 

x=100/10

x=10

Answer 6

x + 2*x + 3*x + 4*x = 100

x*(1 + 2 + 3 + 4) = 100

x*10 = 100

x = 100 : 10

x = 10

Answer 7

\(x+2\cdot x+3\cdot x+4\cdot x=100\)

\(x\cdot\left(1+2+3+4\right)=100\)

\(x\cdot10=100\)

\(x=100:10\)

\(x=10\)

Answer 8

Tìm X biết :

 x + 2x + 3x + 4x = 100

x.( 1 + 2 + 3 + 4 ) = 100

                  x . 10 = 100

                  x       = 100 : 10

                  x       = 10

Answer 9

X + 2 x X + 3 x X 4 = 100

X x ( 1 + 2 + 3 + 4 ) = 100

X x       10                = 100

             X                 = 100 : 10

             X                 =  10

Vậy X = 10

Answer 10

Ta có : x + 2x + 3x + 4x = 100

=> x(1 + 2 + 3 + 4) = 100

=> x . 10 = 100

=> x = 10

Answer 11

\(x+2x+3x+4x=100\)

\(x\left(1+2+3+4\right)=100\)

\(10x=100\)

\(x=100:10\)

\(x=10\)
