Solve the equation by trial and error method
$2p+4=10$

Given:

Given equation is $2p+4=10$.

To do :

We have to solve the given equation by trial and error method.

Solution :

By trial and error method,

If p = 1,

LHS is,

$2(1)+4=2+4=6  RHS = 10$

LHS ≠ RHS

If p = 2,

LHS is,

$2(2)+4=4+4=8  RHS = 10$

LHS ≠ RHS

If p = 3,

LHS is,

$2(3)+4=6+4=10  RHS = 10$

LHS = RHS

Therefore, p=3 is the solution of the given equation.
