Question
Check whether the value given in the brackets is a solution to the given equation or not.
$7 n+5=19(n=-2)$
$7 n+5=19(n=-2)$
✓
Answer
Given equation is $7 n+5=19$.
Here, LHS $=7 n+5$
Puting $n=-2$ in LHS, we get
$
\begin{aligned}
& \text { LHS }=7(-2)+5=-14+5=-9 \neq 19 \\
\because & \text { LHS } \neq \text { RHS }
\end{aligned}
$
So, $n=-2$ is not a solution of the given equation.
