hey everyone, here is my problem, u have to solve this:(adsbygoogle = window.adsbygoogle || []).push({});

x^3 + y^3 = 1

x^4 + y^4 = 1

i tried to solve it but i couldnt, please just give me some hints if you can, thx

i had this one too,

2x+xy+2y = 59

3x-2xy+3y = -34

the teacher told me to do:

2(x+y)+xy=59

3(x+y)-2xy=-34

then,

x+y=12

xy=34

then i solved the equation : x^2-12x+35=0

i got x=5 and x=7

so, the solutions are

x=5 y=7 and x=7 and y=5

i didn t get it, he explained to me but i still don t get why, can anyone explain to me how it was solved???
