Question

11x+15y+25=0
7x-2y-20=0​

Answer 1

Answer:

Here's your answer mate.

Answer 2

7x-2y=20          .... (1)

11x+15y = -23  .... (2)

Multiply equation (1) by 15 and (2) by 2, we get

105x - 30y = 300   ... (3)

22x  + 30y = -46   ... (4)

Adding (3) and (4), we get

127x = 254

→   x = 2

Substitute the value of x = 2 in (1), we get

7(2)-2y=20

→ 2y = -6

→   y = -3

 

Therefore x = 2 and y = -3.
