Question

Hey guys I was not able to understand how to do it . So I have put it in the clip . ​

Answer 1

Step-by-step explanation:

11x + 15y +23 = 0... (1)

7x- 2y -20=0.....equ (2)

multiply equ (1) by 2 & equ( 2 )by 15 and then subtract both change sign

22x + 30y +46=0

+105x + 30y -300=0

- - +

....................................

-83x +346 =0

346 = 83x

346/83 = x

x = 4.1

put in equ (1) or (2) to get y
