Question

tìm x

125 : 29/3 - x = 39

Answer 1

125 : 29/3 - x = 39

          29/3 - x = 125 : 39

          29/3 -x  = 125/39

                    x= 29/3 -125/39

                     x =   252 /39

Answer 2

\(125:\frac{29}{3}-x=39\)

\(\Rightarrow125.\frac{3}{29}-x=39\)

\(\Rightarrow\frac{375}{29}-x=39\)

\(\Rightarrow x=\frac{375}{29}-39\)

\(\Rightarrow x=-\frac{756}{29}\)

Answer 3

\(125:\frac{29}{3}-x=39\)

\(\Rightarrow\frac{125\cdot3}{29}-x=39\)

\(\Rightarrow\frac{375}{29}-x=39\)

\(\Rightarrow x=\frac{375}{29}-39\)

\(\Rightarrow x=\frac{375}{29}-\frac{39}{1}=\frac{375}{29}-\frac{1131}{29}=\frac{-756}{29}\)
