Question

x + 78 * x+ 25 *x - x * 4 = 78,6+121,4

 

Answer 1

x + 78*x + 25*x + x*4=78,6 + 121,4

x*(1+78+25-4)=200

x* 100 =200

x = 200:100

x = 2

Answer 2

\(x+78\times x+25\times x-4\times x=78,6+121,4\)

\(\Rightarrow x\times\left(1+78+25-4\right)=200\)

\(\Rightarrow x\times100=200\)

\(\Rightarrow x=200\div100\)

\(\Rightarrow x=2\)

Vậy x=2

Answer 3

x + 78 * x + 25 * x - x * 4  = 78,6 + 121,4

x * ( 1 + 78 + 25 - 4 ) = 200

                    x * 100 = 200

                             x = 200 : 100

                             x = 2

                        Vậy x = 2

Answer 4

X + 78 x X + 25 x X – X x 4 = 78,6 + 121,4

X + 78 x X + 25 x X – X x 4 = 200

X + (78 + 25 – 4 + 1) = 200

X + 100 = 200

X = 200 : 100

X = 2 

Answer 5

Bài giải:

    X + 78 x X + 25 x X – X x 4 = 78,6 + 121,4

  X =  X x ( 78 + 25 – 4 + 1 ) = 200

  X =  X x 100 = 200

  X =  200 : 100 = 2
