Question

"x-3y=1
5X-74=2
Salve by elimination methods​

Answer 1

Answer:

x-3y = 1 ------------- i

5x -7y = 2----------ii

multiplying i eq with -5

-5x +15y = -5

+5x-7y= 2

» 8y = -3

» y = -3/8

substituting the value of y in eq i

x-3(-3/8)= 1

» x + 9/8= 1

» x = 1-9/8

» x = 8/8 -9/8

» x = -1/8

so the value of x and y are -1/8 and -3/8 respectively
