Express the following statement as a linear equation in two variables. ‘The sum of two numbers is 24″.

The equation $\frac{x}{4}-\frac{y}{7}=3\backslash frac\{x\}\{4\}-\backslash frac\{y\}\{7\}=3$ in linear form is

If (- 3, 2) is a solution of 5x – 8y + k = 0, then the value of k is

If (2, – 1) is a solution of 4x + by + 4 = 0, then the value of ‘b’ is

A line parallel to X – axis is

The number of solutions of 7x – 3y – 15 = 0 is

A line parallel to Y – axis is

The equation of a line parallel to X – axis and passing through (7, – 2) is

If x = 3, y = 2 is a solution of the equation 5x – 7y = k, then the value of ‘k’ is

If x = -3, y = -2 is a solution 5x – 7y = k, then the value of ‘k’
