As both angles are supplementary


\\ \Large\sf\longmapsto 3x+(2x+3y)=180°


\\ \Large\sf\longmapsto 3x+2x+3y=180


\\ \Large\sf\longmapsto 5x+3y=180


\\ \Large\sf\longmapsto 3y=180-5x


\\ \Large\sf\longmapsto y=(180-5x)/(3)

And


\\ \Large\sf\longmapsto 3x=90


\\ \Large\sf\longmapsto x=(90)/(3)


\\ \Large\sf\longmapsto x=30

Now

  • Putting value


\\ \Large\sf\longmapsto y=(180-5x)/(3)


\\ \Large\sf\longmapsto y=(180-5(30))/(3)


\\ \Large\sf\longmapsto y=(180-150)/(3)


\\ \Large\sf\longmapsto y=(30)/(3)


\\ \Large\sf\longmapsto y=10
