Answer 1

Step-by-step explanation:

it can have many solutions if you will take the values of X and Y different different

first take the value of Y in equation first and then put it put it in the value then you will get the value of V similarly do in

Answer 2

Answer:

5x+6y=16........eqn one

2x-2y=2........eqn two

From eqn one we get,

5x+6y =16

or, 5x =16 -6y

or, x =(16-6y)/5

Now putting the value of x in eqn two, we get

2x-2y=2

or, 2×(16-6y)/5-2y =2

or, (32-12y)/5-2y=2

or, (32-12y-10y)/5=2 (LCM)

or, 32-12y-10y=10 (5 gets multiplied with 2)

or, -12y-10y=10-32

or, -22y= -22

or, y=1.

Putting the value of y in eqn one

5x + 6y=6 = 5x + 6×1 =6

= 5x=6-6

=x=0
