Question

3x-5y=-1 and x-y=-1
sabstition method

Answer 1

Answer:

value of x= -2

value of y = -1

Answer 2

Answer:

3x-5y=-1-->(1)

x-y=-1-->(2)

now let

(2)=> x-y=-1

x=y-1-->(3)

now put (3) in (1)

3(y-1)-5y=-1

3y-3-5y=-1

-2y-3=-1

-2y=2

====>y=-1-->(4)

now put (4) in (3)

x=-1-1

x=-2

so x=-2 and y=-1
