Solve for v. 1/2v + 8 = 3 - 1/3v v = ____

Combine like terms: Combine like terms by getting all v terms on one side and constants on the other. 1/2v + 1/3v + 8 = 3 Combine the v terms: (1/2 + 1/3)v + 8 = 3 To add 1/2 and 1/3, find a common denominator, which is 6: (3/6 + 2/6)v + 8 = 3 (5/6)v + 8 = 3 Isolate the v term: Isolate the v term by subtracting 8 from both sides. (5/6)v + 8 - 8 = 3 - 8 (5/6)v = -5 Solve for v: Solve for v by dividing both sides by 5/6. (5/6)v / (5/6) = -5 / (5/6) v = -5 * (6/5) v = -6

Combine like terms: Combine like terms by getting all $v$ terms on one side and constants on the other. $\frac{1}{2}v + \frac{1}{3}v + 8 = 3$ Combine the $v$ terms: $\left(\frac{1}{2} + \frac{1}{3}\right)v + 8 = 3$ To add $\frac{1}{2}$ and $\frac{1}{3}$ , find a common denominator, which is $6$ : $\left(\frac{3}{6} + \frac{2}{6}\right)v + 8 = 3$ $\left(\frac{5}{6}\right)v + 8 = 3$
Isolate the v term: Isolate the v term by subtracting $8$ from both sides. $\newline$ $(\frac{5}{6})v + 8 - 8 = 3 - 8$ $\newline$ $(\frac{5}{6})v = -5$
Solve for $v$ : Solve for $v$ by dividing both sides by $\frac{5}{6}$ . $\frac{\left(\frac{5}{6}\right)v}{\left(\frac{5}{6}\right)} = \frac{-5}{\left(\frac{5}{6}\right)}$ $v = -5 \times \left(\frac{6}{5}\right)$ $v = -6$
