Shyam is plotting a line x − 3y = 6 on the graph. He wrote two solutions of the equation, Solution 1 and Solution 2, as given below in the table.
The pair of equation x+2y+5=0 and -3x-6y+1=0 has
(a) a unique solution (b) exactly two solution
(c) infinitely many solutions (d) no solution
If x=1 and y=6 is a solution of the equation 8x−ay+a2=0, find the values of a.
If x = 3k + 2 and y = 2k - 1 is a solution of the equation 4x - 3y + 1 = 0, find the value of k.
