\newline

\frac{v}{2} + 9 = 12

\newline

v =

\_\_\_\_\_

Start Equation Isolation: Start with the equation $\frac{v}{2} + 9 = 12$ . To isolate $v$ , we need to get rid of the $9$ on the left side of the equation. We can do this by subtracting $9$ from both sides of the equation. $\frac{v}{2} + 9 - 9 = 12 - 9$
Subtract $9$ : Perform the subtraction on both sides. $\newline$ $\frac{v}{2} = 12 - 9$ $\newline$ $\frac{v}{2} = 3$
Simplify Equation: Now we have $\frac{v}{2} = 3$ . $\newline$ To solve for $v$ , we need to get rid of the division by $2$ . $\newline$ We can do this by multiplying both sides of the equation by $2$ . $\newline$ $(\frac{v}{2}) \times 2 = 3 \times 2$
Multiply by $2$ : Perform the multiplication on both sides. $\newline$ $v = 3 \times 2$ $\newline$ $v = 6$
