Question

Tell whether the given value is a solution of the inequality.

$5+\mathrm{j}>8;\mathrm{j}=7$

Answer 1

Checking whether the given value is a solution or not by putting $\mathrm{j}=7$ in given inequality;

$\Rightarrow 5+\mathrm{j}>8$

$\Rightarrow 5+7>8$

$\therefore 12>8$, which is true.

Hence;$\mathrm{j}=7$ is the solution of $5+\mathrm{j}>8$.
