Question

Tìm x:

X - 0,25 = 43/4 + 18/5

Answer 1

x - 0,25 = 43/4 + 18/5

\(x-\frac{1}{4}=\frac{287}{20}\)

\(x=\frac{287}{20}+\frac{1}{4}\)

\(x=\frac{73}{5}\)

 

Answer 2

\(x-0,25=\frac{43}{4}+\frac{18}{5}\)

\(\Rightarrow x-\frac{1}{4}=\frac{43}{4}+\frac{18}{5}\)

\(\Rightarrow x-\frac{1}{4}=\frac{287}{20}\)

\(\Rightarrow x=\frac{287}{20}+\frac{1}{4}\)

\(\Rightarrow x=\frac{73}{5}\)

\(\Rightarrow x=14,6\)

Answer 3

\(x-0,25=\frac{43}{4}+\frac{18}{5}\)

\(x-\frac{1}{4}=\frac{287}{20}\)

\(x=\frac{287}{20}+\frac{1}{4}\)

\(x=\frac{73}{5}\)

Answer 4

\(x-0,25=\frac{43}{4}+\frac{18}{5}\)

\(x-0,25=\frac{287}{20}\)

\(x=14,6\)

Answer 5

Công thức : a-b=c     

                   a= c+b

X-0,25 =43/4 + 18/5

           X= (43/4+ 18/5) + 0,25

            X= 287/20 + 0,25

            X= 73/5

 

            X=
