Question

Tìm x biết:

      x.100+50.100=2500

Tính nhanh đó nha

Answer 1

x.100+50.100=2500

100.(x+50)=2500

x+50=2500:100

x+50=25

x=25-50

x=-25

        Vậy x=-25

Answer 2

\(\Rightarrow100\left(x+50\right)=2500\)

\(\Rightarrow x+50=250\)

\(\Rightarrow x=200\)

Answer 3

\(100x+50.100=2500\)

\(\Rightarrow100x+5000=2500\)

\(100x=2500-5000\)

\(100x=-2500\)

\(\Rightarrow x=-2500:100\)

Vậy x = -25

Answer 4

\(100\left(x+50\right)=2500\)

\(\Rightarrow x+50=25\)

\(\Rightarrow x=25-50\)

\(\Rightarrow x=-50\)

Answer 5

x = 2500 - 50.100

x = -2500

x = -2500 : 100

x = -25
