Question

solve the pair of linear equations 3x-5y=-1 and x-y=-1 by elimination method​

Answer 1

Answer:

3x-5y=-1

x-y=-1

therefore,

3(x-y)=-1×3

3x-3y=-3

Step-by-step explanation:

now,

3x-5y=-1

Substracting the above equations,we get:

-2y=2

therefore;

y=-1

x=-2

Answer 2

Answer:

3(x-y=-1)

3x-3y=-3

3x-5y=-1

3x-3y=-3

-. + +

___________

-2y=2

y=-1

substituting y=-1 in eq 1

3x-5(-1)=-1

3x+5=-1

3x=-6

x=-2
