=>15/10x+25=60.2/3
=>15/10x+25=40
=>15/10x=40-25
=>15/10x=15
=>x=15.10/15
=>x=10
vậy x=10
\(\left(\frac{15}{10}x+25\right):\frac{2}{3}=60\)
\(\Rightarrow\frac{15}{10}x+25=60\cdot\frac{2}{3}\)
\(\Rightarrow\frac{10}{15}x+25=40\)
\(\Rightarrow\frac{10}{15}x=40-25\)
\(\Rightarrow\frac{10}{15}x=15\)
\(\Rightarrow x=15:\frac{10}{15}\)
\(\Rightarrow x=\frac{45}{2}\)
