Question

- 1/2 - 2/3v = 4/5 please help

Answer 1

Answer:

v = - $\frac{39}{20}$

Step-by-step explanation:

Given

- $\frac{1}{2}$ - $\frac{2}{3}$ v = $\frac{4}{5}$

Multiply through by 30 ( the LCM of 2, 3 and 5 )

- 15 - 20v = 24 ( add 15 to both sides )

- 20v = 39 ( divide both sides by - 20 )

v = - $\frac{39}{20}$

Answer 2

Answer:

$v=-\frac{39}{20}$

Step-by-step explanation:

Given the expression

$-\frac{1}{2}-\frac{2}{3}v=\frac{4}{5}$

Add 1/2 to both sides

$-\frac{1}{2}-\frac{2}{3}v+\frac{1}{2}=\frac{4}{5}+\frac{1}{2}$

$-\frac{2}{3}v=\frac{13}{10}$

Multiply both sides by 3

$3\left(-\frac{2}{3}v\right)=\frac{13\cdot \:3}{10}$

$-2v=\frac{39}{10}$

Divide both sides by -2

$\frac{-2v}{-2}=\frac{\frac{39}{10}}{-2}$

$v=-\frac{39}{20}$

Therefore,

$v=-\frac{39}{20}$
