Question

IS P = 7 a solution of a the inequation P+3>9?​

Answer 1

Answer:

$P=7$ is the correct solution for equation  $P+3>9$

Step-by-step explanation:

Given : $P+3>9$

To find : If $P=7$ is a solution of the equation  $P+3>9$.

Solution :

• It is given that the equation is  $P+3>9$
• We have to find that $P=7$ is the correct solution for given equation or not.
• We know that inequality symbols are >, < and =.

      Ex. i) a>b,

       > symbol denotes that a is greater than b.

           ii) a<b

       < symbol denotes that a is less than b.

           iii) a=b

        = symbol denotes that a is equal to b.

• Now,

        To find whether $P=7$ is a solution of given equation or not, we have to put $P=7$ in given equation.

           $P+3>9$

          ∴  $7+3>9$

             ∴  $10>9$

• ∴  $P=7$ is the correct solution for equation  $P+3>9$.
