Answer:

y - x + 3 = 0

=> y = x + 3 ---(1)

x^2 - x = 6 + y

by using (1)

=> x^2 - x = 6 + x + 3

=> x^2 - x - x = 9

=> x^2 - 2x = 9

=> x^2 - 2x - 9 = 0

=> x = -b +/- √(b^2-4ac)/2a

=> x = -(-2) +/- √[ (-2)^2 - 4×1×(-9)]/ 2×1

=> x = 2 +/- √[ 4 - (-36)]/2

=> x = 2 +/- √40/2

=> x = 2 +/- (2√10)/2

=> x = 2 + √10 ; x = 2 - √10

=> y = (2 + √10) + 3 ; y = (2 - √10) + 3

=> y = 10+5 ; y = 10 +1
