5x - 4y = 42 ------ (1)
x - 6y = 24 ----------(2), multiply eq. 2 by 5 we get
5x - 30y = 120 -----(3),
now use eq. (3) - (1),
5x - 30y = 120
-(5x - 4y = 42)
- 30y + 4y = 120 - 42,
-26y = 78, y = -78/26 = -3,
x = 24 + 6y = 24 + (6*[-3]) = 24 - 18 = 6,
x = 6, y = -3.

i think it' =-8abc(a+b-c)

Answer:
(x + 3)² + (y + 6)² = 2²
Step-by-step explanation:
General form
(x - h)² + (y - k)² = r²
(h, k) is the center = (-3, -6)
r is the rradius = 2
-----------------------
(x + 3)² + (y + 6)² = 2²
