Answer:

2x+3y-7=0

6x+5y-11=0

we will take the 7th and the 11th term to other side

2x+3y=7.......1

6x+5y=11......2

while taking the number to your right hand side the signs will change -7 will become 7 and -11 will become 11

2x+3y=7......3

6x+5y=11.......4

multiplying the 3rd term by 5

multiplying the 4th term by 3

10x+15y=35....5

18x+15y=33.....6

- - -.......by subtracting ( signs will change)

15y will get cancelled because of - and + signs

=-8x=2

x=-8 upon 2

x=-4

substituting the value x=-4 in equation no 1

2x+3y=7.....(1)

2(-4) +3y = 7

-8+3y =7

3y =7+8....(- sign will become + )

3y=15

y=15 upon 3

y= 5

Answer

x=-4 and y=5
