plotting – How to draw several contours label in separate colors

Good morning. I have two equations (or more) that I want plot with ContourPlot colored with different colours and labelled according to equation order, in a automatic way. I have tried several solutions without success. My plot should remain as

g1 = x + 2 y; g2 = 2 x + y; b = {2, 2};

coloresRest = {Blue, Magenta}; labelRest = Table(Text(Style(“(” <> ToString@i <> “)”, coloresRest((i)))), {i, Length@coloresRest});

ContourPlot({g1 == b(1), g2 == b((2))}, {x, -2, 4}, {y, -2, 4}, Frame -> False, Axes -> True, ContourStyle -> Thread({coloresRest, grosor}), Epilog -> {Text(Style(“(1)”, color3), Offset({20, 0}, {-2, 2})), Text(Style(“(2)”, color4), Offset({-10, -10}, {-1, 4}))}, ImageSize -> 400)

enter image description here

I have tried with Table, ContourLabel, Riffle or Epilog, without success. For example:

ContourPlot({g1 == b(1), g2 == b((2))}, {x, -2, 4}, {y, -2, 4}, Frame -> False, Axes -> True, ContourStyle -> Thread({coloresRest, grosor}), ContourLabels -> Table(Text(Style(labelRest((i)), Offset({10, 0}, {#1, #2} &))), {i, 1, Length@coloresRest}), ImageSize -> 400)

or

ContourPlot({g1 == b(1), g2 == b((2))}, {x, -2, 4}, {y, -2, 4}, Frame -> False, Axes -> True, ContourStyle -> Thread({coloresRest, grosor}), ContourLabels -> {Riffle(coloresRest, Inset(labelRest, Offset({10, 0}, {#1, #2} &)))}, ImageSize -> 400)

I realize that expresión {#1, #2}& yield coordinates for labels, choosen by Mathematica. I’d prefer that and not to choose such coordinates.

Thank in advance
