Question

Solve the equation. What is the value of v?
One way you can start solving is to make sure there are only v terms on one side. What move can you make to both sides of the equation to get rid of the

​
v on the left, while keeping the equation balanced?
4

​
v + 8
=
v + 12

Multiply both sides by

v

Add

Nice!
You can subtract

v from the left side of the equation, so that the v terms are only on the right side of the equation, while keeping the equation balanced. Record subtracting

Great job!
We have v terms on both sides of the equation, and we want to get the v terms on one side. We can subtract

​
v on the left side of the equation so that there are no v terms on the left. Then we need to subtract

v from the right to keep the equation balanced. Go for it.

Great job!
Keep going. Let's try to get

v + 12

Divide both sides by 12

Add 12 to both sides

Subtract 12 from both sides

Answer 1

Let's start from where we were after the steps you outlined. The equation we had was:

\[
8 = v + 12 - \frac{4}{3}v
\]

Now, we need to simplify the right side by combining the \(v\) terms. By rearranging and simplifying the equation, we can write it as:

\[
8 = v - \frac{4}{3}v + 12
\]

Now, we express \(v\) terms as:

\[
v - \frac{4}{3}v = \frac{3}{3}v - \frac{4}{3}v = -\frac{1}{3}v
\]

So the equation simplifies to:

\[
8 = -\frac{1}{3}v + 12
\]

Next, we want to eliminate the \(12\) on the right side. We can do this by subtracting \(12\) from both sides:

\[
8 - 12 = -\frac{1}{3}v
\]

This simplifies to:

\[
-4 = -\frac{1}{3}v
\]

Now, to get \(v\) alone, we can multiply both sides by \(-3\):

\[
-4 \times -3 = v
\]

Thus:

\[
v = 12
\]

So the final answer is:

\[
\boxed{12}
\]
