2/3n frac- 6 =-8

1 answer

To solve the equation \( \frac{2}{3}n - 6 = -8 \) using inverse operations, follow these steps:

Step 1: Isolate the term with the variable

First, we need to eliminate the constant term on the left side. We can do this by adding 6 to both sides of the equation:

\[ \frac{2}{3}n - 6 + 6 = -8 + 6 \]

Simplifying both sides gives:

\[ \frac{2}{3}n = -2 \]

Step 2: Solve for \( n \)

Next, we need to get \( n \) by itself. To do this, we can multiply both sides of the equation by the reciprocal of \( \frac{2}{3} \), which is \( \frac{3}{2} \):

\[ \frac{3}{2} \cdot \frac{2}{3}n = -2 \cdot \frac{3}{2} \]

The left side simplifies as follows:

\[ 1n = -2 \cdot \frac{3}{2} \]

Now calculating the multiplication on the right:

\[ n = -2 \cdot \frac{3}{2} = -\frac{6}{2} = -3 \]

So the solution to the equation is:

\[ n = -3 \]

Step 3: Check the Answer

To verify our solution, we will substitute \( n = -3 \) back into the original equation:

\[ \frac{2}{3}(-3) - 6 = -8 \]

Calculating the left side, we have:

\[ \frac{2 \cdot -3}{3} - 6 = -2 - 6 = -8 \]

This matches the right side of the equation, confirming our solution is correct.

Final Answer

The solution is \( n = -3 \).
