Answer 1

Question:

Solve the following equation by the trial and error method: $\frac {P}{2}+6=9$

Method of Solution:

$\frac {P}{2}+6=9$

$\frac{p}{2} = 9 - 6 \\ \\ \frac{p}{2} = 3 \\ \\ p = 3 \times 2 \\ = 6$


Verification:

Substitute the value of p in the given Equation!

p/2 + 6 =9

6/2 + 6= 9

3+6 = 9

9=9


Hence, LHS is Equal to RHS

Answer 2

$\frac{P}{2} + 6 = 9 \\ \frac{P}{2} = 9 - 6 \\ P = 3 \times 2 \\ P = 6$
