10x + 3/12 = 1 + 6 + 8x/9
<=> 10x + 3/2 = 7 + 3x/9
<=> 180x + 27 = 126 + 16x
<=> 180x - 16x = 126 - 27
<=> 164x = 99
<=> x = 99/164
<=> \(10x+\frac{1}{4}=7+\frac{8x}{9}\)
<=> \(\left(10-\frac{8}{9}\right)x=7-\frac{1}{4}\)
<=> \(\frac{82}{9}x=\frac{27}{4}\)
<=> \(x=\frac{243}{328}\).
\(10x+\frac{3}{12}=1+6+\frac{8x}{9}\)
\(10x-\frac{8}{9}x=1+6-\frac{3}{12}\)
\(\frac{82}{9}x=1+6-\frac{1}{4}\)
\(\frac{82}{9}x=\frac{27}{4}\)
\(x=\frac{27}{4}:\frac{82}{9}\)
\(x=\frac{243}{328}\)
