Answer 1

Hey friend !

Here's your answer

========================>

1.) Expressing the equation 3x =5y +7 into ax + by + c =0

3x -5y -7 =0. is the answer for above question

The value of c is 7

2.) Given two equations ,

3x + y =2

5x -2y =7

and given ( -2 , 1 )

Here x can be taken as -2 and y as 1

Now substituting above values in equations .

3 (-2) + (1) = 2

-6 + 1 =2

-5 = 2

Second equation

5 (-2) - 2(1) =7

-10 -2 = 7

-12 =7

LHS is not equal to RHS in the above case.

So, the values of x and y are wrong.
