color(blue)(y = (2 + x) / (5x - 1)

Explanation:

x = (color(blue)(y)+2) / (5color(blue)(y) -1)

Our main motive in solving this question should be to isolate color(blue)(y:

x * (5color(blue)(y) -1) = color(blue)(y)+2

We multiply x with both terms within the bracket.

x * (5color(blue)(y)) + x *( -1) = color(blue)(y)+2

5xcolor(blue)(y) -x = color(blue)(y)+2

5xcolor(blue)(y) - color(blue)(y) = 2 + x

color(blue)(y)(5x - 1) = 2 + x

color(blue)(y = (2 + x) / (5x - 1)
