118,24-(X:5+Xx3)=54,24

Answer 1

[wattif]

118,24-(X:5+Xx3)=54,24

118,24-x:(5+1/3)=54,24

118,24-x:16/3=54,24

x:16/3=64

x=1024/3

Vậy x=1024/3

Answer 2

[╰Nguyễn Trí Nghĩa (team toán học)ッ...]

\(118,24-\left(x:5+x.3\right)=54,24\)

\(\Rightarrow118,24-\left(x.0,2+x.3\right)=54,24\)

\(\Rightarrow118,24-\left[x.\left(0,2+3\right)\right]=54,24\)

\(\Rightarrow118,24-3,2x=54,24\)

\(\Rightarrow3,2x=118,24-54,24\)

\(\Rightarrow3,2x=64\)

\(\Rightarrow x=64:3,2\)

\(\Rightarrow x=20\)

Vậy x=20
