1.7x−0.17=1.2x+0.12  1.7x−1.2x=0.12+0.17  0.5x=0.29  x=((0.29)/(0.5))=((29×10)/(100×5))=((29×2)/(100))=0.58
$$\mathrm{1}.\mathrm{7}{x}−\mathrm{0}.\mathrm{17}=\mathrm{1}.\mathrm{2}{x}+\mathrm{0}.\mathrm{12} \\ $$$$\mathrm{1}.\mathrm{7}{x}−\mathrm{1}.\mathrm{2}{x}=\mathrm{0}.\mathrm{12}+\mathrm{0}.\mathrm{17} \\ $$$$\mathrm{0}.\mathrm{5}{x}=\mathrm{0}.\mathrm{29} \\ $$$${x}=\frac{\mathrm{0}.\mathrm{29}}{\mathrm{0}.\mathrm{5}}=\frac{\mathrm{29}×\mathrm{10}}{\mathrm{100}×\mathrm{5}}=\frac{\mathrm{29}×\mathrm{2}}{\mathrm{100}}=\mathrm{0}.\mathrm{58} \\ $$

by componendo & dividendo  ((x−0.1+x+0.1)/(x−0.1−x−0.1))=((1.2+1.7)/(1.2−1.7))  ((2x)/(−0.2))=((2.9)/(−0.5))  x=((29)/5)×0.1=0.58
$${by}\:{componendo}\:\&\:{dividendo} \\ $$$$\frac{{x}−\mathrm{0}.\mathrm{1}+{x}+\mathrm{0}.\mathrm{1}}{{x}−\mathrm{0}.\mathrm{1}−{x}−\mathrm{0}.\mathrm{1}}=\frac{\mathrm{1}.\mathrm{2}+\mathrm{1}.\mathrm{7}}{\mathrm{1}.\mathrm{2}−\mathrm{1}.\mathrm{7}} \\ $$$$\frac{\mathrm{2}{x}}{−\mathrm{0}.\mathrm{2}}=\frac{\mathrm{2}.\mathrm{9}}{−\mathrm{0}.\mathrm{5}} \\ $$$${x}=\frac{\mathrm{29}}{\mathrm{5}}×\mathrm{0}.\mathrm{1}=\mathrm{0}.\mathrm{58} \\ $$
