Real numbers x and y satisfy
x+xy2=250y,x−xy2=−240y.
find all values of x separated by commas
I've been really stuck and whatever I did didn't get me anywhere. Thank you to anyone who answers :)
Use elimination method
First add the 2 equations
x+x+xy2+−xy2=250y+−240y2x=10yx=5y
Now sub that into either original equation and solve for y there might be more than one answer.
See if you can go from there.
