Question

6x-5y-11=0
10x+3y=75

find x,y by elemination method

2x+3y=-1
-4x+7=3y

find x,y by elemination method​

Answer 1

6x-5y=11......i

10x+3y=75.....ii

eq i*3 +ii*5

18x - 15y= 33

50x + 15y= 375

68x+0= 408

x=408/68= 6

put the value of x in eq i

6x-5y=11

6*6-5y=11

-5y= 11-36

-5y= -25

y= 25/5= 5

x=6;y=5
