Question

(1) 2x+3y = 1
3x-y = 7
(ii) x + 2y = 6
2x + 4y = 12
(m) 3x + 2y = 6
6x + 4y = 18
TRY THISO
paralle
y=5
For what value of 'p' the following pair of equations has a unique solution.
1.
2x + py = - 5 and 3x + 3y = -6
2. Find the value of 'k' for which the pair of equations 2x - ky + 3 = 0, 4x + 6y - 5 =0
represent parallel lines.
3. For what value of 'k', the pair of equations 3x + 4y + 2 = 0 and 9x + 12y + k = 0
represents coincident lines.
4. For what positive values of'p', the following pair of linear equations have infinite solutions
pur + 3y - (p - 3) = 0
12x + py - p = 0
Let us look at some more examples.
Example-4. In a garden there are some bees and flowers. If one bee sits on each flower
(1.
