Question

solve for v.
-21 = 7v
simplify your answer as much as possible.
v =

Explanation:

Step1: Divide both sides by 7

To solve for \( v \) in the equation \( -21 = 7v \), we divide both sides of the equation by 7. This is because we want to isolate \( v \), and since \( v \) is multiplied by 7, we use the inverse operation of multiplication, which is division. So we have:

$$ \frac{-21}{7}=\frac{7v}{7} $$

Step2: Simplify both sides

Simplifying the left side, \( \frac{-21}{7}=-3 \). On the right side, \( \frac{7v}{7}=v \) (because the 7 in the numerator and denominator cancels out). So we are left with:
\( v = -3 \)

Answer:

\( v = -3 \)
