Question

Solve the equations:
(x-1)^2+(y+2)^2=8,
x^2+y^2-3x+y=12.


ANSWER {(3,-4),(-9/5,-12/5)}

Answer 1

subtract first from the second and find y in terms of x

Answer 2

i think i have 2 simplify the 2 equations first then subtract them

Answer 3

yup

Answer 4

(x-1)^2+(y+2)^2=8
x^2-2x+1+y^2+4y+4=8
x^2+y^2-2x+4y-3=0---------( equation 1)

Answer 5

x^2+y^2-3x+y=12
x^2+y^2-3x+y-12=0---------(equation 2)

Answer 6

am i doing it right

Answer 7

right

Answer 8

Subtraction
