\\ \sf\longmapsto 2x+25=3x-10


\\ \sf\longmapsto 25+10=3x-2x


\\ \sf\longmapsto x=35\checkmark

Now


\\ \sf\longmapsto (2y+50)/(5y-17)=(7x-248)/(x+44)


\\ \sf\longmapsto (2y+50)/(5y-17)=(7(35)-248)/(35+44)


\\ \sf\longmapsto (2y+50)/(5y-17)=(-3)/(79)


\\ \sf\longmapsto 79(2y+50)=-3(5y-17)


\\ \sf\longmapsto 158y+3950=-15y+51


\\ \sf\longmapsto 158y+15y=51-3950


\\ \sf\longmapsto 173y=-3899


\\ \sf\longmapsto y=22.3
