Solve 2=1/3v^2/7v-3/8v

Evaluate

2 = \frac{1}{3} \times \frac{v ^{2}}{7} v - \frac{3}{8} v

Multiply the terms

More Steps

2 = \frac{v ^{3}}{21} - \frac{3}{8} v

Swap the sides of the equation

\frac{v ^{3}}{21} - \frac{3}{8} v = 2

Multiply both sides of the equation by LCD

(\frac{v ^{3}}{21} - \frac{3}{8} v) \times 168 = 2 \times 168

Simplify the equation

More Steps

8 v^{3} - 63 v = 2 \times 168

Simplify the equation

8 v^{3} - 63 v = 336

Move the expression to the left side

8 v^{3} - 63 v - 336 = 0

Solution

v \approx 4.221779
