Question

please give me the answer of this question, find the value of X and Y, by Cramer's method.​

Answer 1

Hey mates!!

let the fraction is x/y

Then by the given question,

(x+2) / (y+2) = 9/11

11x + 22 = 9y + 18

11x - 9y = 18-22

11x -9y = -4

11x = 9y -4

x = (9y - 4)/11

and, (x+3)/ (y+3) = 5/6

6x + 18 = 5y + 15

6x - 5y = 15 - 18

6(9y -4)/11 - 5y = -3

(54y - 24- 55y)11 = -3

-y -24= -3 ×11

y + 24 =33

y= 33- 24 =9

x= (9×9-4)/11

x=(81-4)/11

x=77/11

x= 7, y= 9 and the fraction is 7/9

plz mark me as brain list..... plz
