Solve for v. v/2 + 9 = 12 v = _____

Start Equation Isolation: Start with the equation 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. v/2 + 9 - 9 = 12 - 9Subtract 9: Perform the subtraction on both sides. v/2 = 12 - 9 v/2 = 3Simplify Equation: Now we have v/2 = 3. To solve for v, we need to get rid of the division by 2. We can do this by multiplying both sides of the equation by 2. (v/2) * 2 = 3 * 2Multiply by 2: Perform the multiplication on both sides. v = 3 * 2 v = 6

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. $\newline$ $v = 3 \times 2$ $\newline$ $v = 6$
