\(\frac{56-x}{34}=\frac{144}{96}=\frac{3}{2}\)
\(\Rightarrow\left(56-x\right)2=34\cdot3=102\)
\(\Rightarrow56-x=102\div2\)
\(\Rightarrow56-x=51\)
\(\Rightarrow x=56-51\)
\(\Rightarrow x=5\)
\(56-\frac{x}{34}=\frac{144}{96}\)
\(\Rightarrow\frac{x}{34}=56-\frac{144}{96}\)
\(\Rightarrow\frac{x}{34}=\frac{109}{2}\)
\(\Rightarrow2x=109\cdot34=3706\)
\(\Rightarrow x=3706\div2\)
\(\Rightarrow x=1853\)
\(56-\frac{x}{34}=\frac{144}{96}=\frac{3}{2}\)
\(\Rightarrow\frac{x}{34}=56-\frac{3}{2}\)
\(\Rightarrow\frac{x}{34}=\frac{109}{2}\)
\(\Rightarrow2x=109\cdot34=3706\)
\(\Rightarrow x=3706\div2=1853\)
không phải x = 1853 đâu.mình làm trên violympic thấy sai rồi
