$S (t) = 2 t \frac{3}{2} - 9 t + 6$

Step 1

Since $t$ is on the right side of the equation, switch the sides so it is on the left side of the equation.

$2 t (\frac{3}{2}) - 9 t + 6 = S t$

Step 2

Step 2.1.1.1

Factor $2$ out of $2 t$ .

$2 (t) \frac{3}{2} - 9 t + 6 = S t$

Step 2.1.1.2

Cancel the common factor.

$2 t \frac{3}{2} - 9 t + 6 = S t$

Step 2.1.1.3

Rewrite the expression.

$t \cdot 3 - 9 t + 6 = S t$

Step 2.1.2

Move $3$ to the left of $t$ .

$3 t - 9 t + 6 = S t$

Step 2.2

Subtract $9 t$ from $3 t$ .

$- 6 t + 6 = S t$

Step 3

Subtract $S t$ from both sides of the equation.

$- 6 t + 6 - S t = 0$

Step 4

Subtract $6$ from both sides of the equation.

$- 6 t - S t = - 6$

Step 5

Factor $t$ out of $- 6 t - S t$ .

Step 5.1

Factor $t$ out of $- 6 t$ .

$t \cdot - 6 - S t = - 6$

Step 5.2

Factor $t$ out of $- S t$ .

$t \cdot - 6 + t (- S) = - 6$

Step 5.3

Factor $t$ out of $t \cdot - 6 + t (- S)$ .

$t (- 6 - S) = - 6$

Step 6

Divide each term in $t (- 6 - S) = - 6$ by $- 6 - S$ and simplify.
