How many linear equations in x and y can be satisfied by x = 1 and y = 2?
If x = 2k + 1 and y = k − 1 is a solution of the equation 2x − 3y + 5 = 0, find the value of k.
Write two solutions of the equation: −4x + 3y = 12.
For what value of c, the linear equation cx + 3y = 24 has equal values of x & y for its solution.
Assertion (A): A linear equation 2x + 3y = 5 has a unique solution. Reason (R): A linear equation in two variables has infinitely many solutions.
Find four different solutions of the equation x + 2y = 6.
