Question

solve the following equation by elimination method ​

Answer 1

Step-by-step explanation:

this is Answer of your question

Answer 2

3(X-Y)+4(2x-y)=11

3x-3y+8x-4y=11

11x-7y= 11 ..........,(1)

7/2(4x-13y)= 5(x-27y)+9

28/2x-91/2y= 5x-135y+9

14x-91/2y= 5x-135y+9

9x+179/2y= 9

18x+ 179y= 18 ..........,...(2)

multiplying by 18 in (1) and by11 in (2) we have

198x-126y= 198 ...........(3)

198x+1979y= 198...........(4)

hence. y=0

and. x= 1
