To solve the linear equation \( \frac{2}{9}x + 5 = -10 \), we can follow these steps:
-
Isolate the term with \( x \): Subtract 5 from both sides of the equation. \[ \frac{2}{9}x + 5 - 5 = -10 - 5 \] This simplifies to: \[ \frac{2}{9}x = -15 \]
-
Eliminate the fraction: Multiply both sides of the equation by \( \frac{9}{2} \) to solve for \( x \). \[ x = -15 \cdot \frac{9}{2} \]
-
Calculate the right side: \[ x = -15 \cdot \frac{9}{2} = -\frac{135}{2} \]
So, the solution is: \[ x = -\frac{135}{2} \]
In decimal form, this can be expressed as: \[ x = -67.5 \]
Thus, the final answer is: \[ x = -\frac{135}{2} \quad \text{or} \quad x = -67.5 \]
