2 times 2=4
multiply first equation by 2 to get
-4x+6y=12
then add to get

-4x+6y=12
<u>4x-2y=8 +</u>
0x+4y=20

4y=20
y=5

sub back
-2x+3y=6
-2x+3(5)=6
-2x+15=6
-2x=-9
x=9/2=4.5

Find a polar equation that has the same graph as the equation in x and y.<br> x^2 + y^2 = 5
Alex17521 [72]
X^2 + y^2 can be replaced by r^2 to obtain the polar equation equivalent to x^2 + y^2 = 5.  Thus, r^2 = 5, and r = sqrt(5).  That's all that's necessary.  No matter what the angle is, r will always be sqrt(5).
