- 22 - 7v = - 3(8V + 4)<br> Round to the nearest hundreth

Dmitriy789 [7]

Answer:

v = 0.58

Step-by-step explanation:

-22 - 7v = -3(8v + 4)

Expand -3(8v + 4)

3 * 8v - 3 * 4

Simplify -3 * 8v -3 * 4

= -24v - 12

-22 - 7v = -24v - 12

Add 22 to both sides

-7v = -24v +10

Add 24v to both sides

17v = 10

$\frac{17v}{17} =\frac{10}{17}$

$v =\frac{10}{17}$

$v=0.58$
