Answer:
x = 0.781 , y = -1.219
and
x = -1.281 , y = -3.281.
Step-by-step explanation:
Since both of the x terms are equal to y we can equate the x terms:-
-2x^2 = x - 2
2x^2 + x - 2 = 0
x = [-1 +/- √(1^2 - 4*2*-2) ] / 4
= ( - 1 +/- √(17)) / 4
= 0.781, -1.281.
When x = 0.781 y = 0.781 - 2 = -1.219.
when x = -1.281 , y = -1.281 - 2= -3.281.
