0.25(×+2)=0.5(2×−1)
$$\mathrm{0}.\mathrm{25}\left(×+\mathrm{2}\right)=\mathrm{0}.\mathrm{5}\left(\mathrm{2}×−\mathrm{1}\right) \\ $$

i think × represent x   0.25(x+2)=0.50(2x−1)  x+2=2(2x−1)  x+2=4x−2  x−4x=−2−2  −3x=−4  x=(4/3)
$${i}\:{think}\:×\:{represent}\:{x}\: \\ $$$$\mathrm{0}.\mathrm{25}\left({x}+\mathrm{2}\right)=\mathrm{0}.\mathrm{50}\left(\mathrm{2}{x}−\mathrm{1}\right) \\ $$$${x}+\mathrm{2}=\mathrm{2}\left(\mathrm{2}{x}−\mathrm{1}\right) \\ $$$${x}+\mathrm{2}=\mathrm{4}{x}−\mathrm{2} \\ $$$${x}−\mathrm{4}{x}=−\mathrm{2}−\mathrm{2} \\ $$$$−\mathrm{3}{x}=−\mathrm{4} \\ $$$${x}=\frac{\mathrm{4}}{\mathrm{3}} \\ $$
