Express y in terms of x, given that Check whether ( – 5, 2) is a solution of the given equation.

For point ( – 5, 2), x = – 5 and y = 2. Putting these values in we get,

Now, for

R.H.S

Since, RHS = LHS, therefore, yes ( – 5, 2) is a solution of

Find the value of k, if x = 3, y = 1 is a solution of the equation 2x + 5y = k.

Find four different solutions of 2x + y = 6.

Show that (3, 1) as well as (2, – 2) are the solutions of the equation 3x – y = 8. Find two more solutions. How many solutions can we find?

For the equation 6x – 5y = 8, verify that

(i) (3, 2) is a solution (ii) (2, 3) is not a solution
