Answer 1

Answer:

x = 2;   y = -3

Step-by-step explanation:

11x + 15y + 23 = 0

7x - 2y - 20 = 0

Multiplying eq (i) by 2 and eq (ii) by 15 and adding both

22x + 30y + 46 = 0

105x - 30y - 300 = 0

------------------------------

127x - 254 = 0

x = 2

Substituting in eq (ii)

2y = 7x2 - 20

⇒ 2y = -6

⇒ y = -3  

Answer 2

Answer:

by solving we get

X=2

y= -3
