Solution

The correct option is D 4
We know that the value of the variable for which the equation is satisfied is called the solution of the equation.

By substituting p = -2 in the LHS of the given equation, we get
4p - 3 = 4(-2) - 3 = -11, which is not equal to the RHS of the given equation.
Hence -2 is not the solution of the equation $4 p - 3 = 13$ .

By substituting p = 2 in the LHS of the given equation, we get
4p - 3 = 4(2) - 3 = 5, which is not equal to the RHS of the given equation.
Hence 2 is not the solution of the equation $4 p - 3 = 13$ .

By substituting p = -4 in the LHS of the given equation, we get
4p - 3 = 4(-4) - 3 = -19, which is not equal to the RHS of the given equation.
Hence -4 is not the solution of the equation $4 p - 3 = 13$ .

By substituting p = 4 in the LHS of the given equation, we get
4p - 3 = 4(4) - 3 = 13, which is equal to the RHS of the given equation.
Hence 4 is the solution of the equation $4 p - 3 = 13$ .
