Question

{xy+x²=10
{xy+y2=15
Help me!!!!!

Answer 1

xy+x²=10
xy+y²=15

x*(y+x)=10
y*(y+x)=15

x/y=2/3

x=2/3*y

2/3*y*y+y²=15

y=3
y=-3

x*3+x²=10
x*(-3)+x²=15

x=2
x=-5
x=5
x=-2

x1=2
y1=3
x2=-5
y2=3
x3=5
y3=-3
x4=-2
y4=-3

2*3+2²=10
2*3+3²=15

-5*3+(-5)²=10
-5*3+3²=15

5*(-3)+5²=10
5*(-3)+(-3)²=15

-2*(-3)+(-2)²=10
-2*(-3)+(-3)²=15

10=10
15=15

10=10
-6=15

10=10
-6=15

10=10
15=15

x1=2
y1=3
x2=-2
y2=-3
