Verify that $ y=9 $ is the solution of the equation $ \frac{y}{3}+5=8 $.
Given:
\( \frac{y}{3}+5=8 \).
To do:
We have to verify whether \( y=9 \) is the solution of the equation \( \frac{y}{3}+5=8 \).
Solution:
If $x=a$ is a solution of the equation $f(x)=0$ then $f(a)=0$.
Therefore,
To verify whether \( y=9 \) is the solution of the equation \( \frac{y}{3}+5=8 \), let us substitute the value of $y$ in the given equation.
LHS
$\frac{y}{3}+5=\frac{9}{3}+5$
$=3+5$
$=8$
RHS$=$8
Hence, \( y=9 \) is the solution of the equation \( \frac{y}{3}+5=8 \).
