Question

solve by addition method 3x^2-4y^2=-13, 2x^2+5y^2=22

Answer 1

3x^2 -4y^2 =-13 ;*2
2x^2 +5y^2 =22 ;*-3


6x^2 -8y^2 =-26
-6x^2 -15y^2 =-66
-------------------
0 -23y^2 = -92

y = sqrt(92/23)

Answer 2

y = +- sqrt(92/23)..sooo

3x^2 - 4(92)/23 = -13

Answer 3

x^2 = -13 +4(9)/23
------------
3


x = -13 +4(9)/23
sqrt( ------------ )
