2/3n - 6= -8

solve by using inverse operations

1 answer

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

  1. Add 6 to both sides to eliminate the constant term on the left side:

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

This simplifies to:

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

  1. Multiply both sides by the reciprocal of \(\frac{2}{3}\), which is \(\frac{3}{2}\):

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

Calculating the right side:

\[ n = -3 \]

So, the solution to the equation is:

\[ n = -3 \]

You can verify this by substituting \(n = -3\) back into the original equation:

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

The left side equals the right side, confirming that the solution \(n = -3\) is correct.
