\(\frac{3x-0.8}{x}+14.5=15\)
\(3-\frac{0.8}{x}=15-14.5\)
\(3-\frac{0.8}{x}=0.5\)
\(\frac{0.8}{x}=3-0.5\)
\(\frac{0.8}{x}=2.5\)
\(x=\frac{0.8}{2.5}=\frac{8}{25}\)
\(\frac{3\cdot x-0.8}{x}+14.5=15\)
\(\frac{3\cdot x-0.8}{x}=15-14.5\)
\(\frac{3\cdot x-0.8}{x}=\frac{1}{2}\)
\(2\cdot\left(3\cdot x-0.8\right)=x\cdot1\)
\(6\cdot x-1.6=x\)
\(6\cdot x-x=1.6\)
\(5\cdot x=1.6\)
\(x=1.6:5\)
\(x=0.32\)
