Solution ⬇️

✍️2x+3y=2..(1)

✍️x-2y=8..(2)x²

✍️2x-4y=16..(3) multiplying equation 2 by 2

✍️(-)2x(-)+3y=(-)2..(1) subtracting equation 3 and 1

_________________

✳️-7y=14

_________________

$= = > y = - \frac{14}{7} = - 2$

➡️ Substituting value y=-2 in equation 2

✍️ x-2y=8..(2)

✍️x-2(-2)=8

✍️x-4=8

✍️x=8+4

________

✳️x=12

________

➡️(x,y)(12,-2) is the solution of the given quadratic equation
