Answer
The equation has one solution.
$t=\frac{3}{8}$
Work Step by Step
The given equation is
$\Rightarrow 9+4t=12-4t$
Add $4t-9$ to each side.
$\Rightarrow 9+4t+4t-9=12-4t+4t-9$
Simplify.
$\Rightarrow 8t=3$
Divide each side by $8$.
$\Rightarrow \frac{8t}{8}=\frac{3}{8}$
Simplify.
$\Rightarrow t=\frac{3}{8}$
Hence, the equation has one solution.
$t=\frac{3}{8}$
