To solve the equation \(-6x - 10 = 20\), follow these steps:
-
Add 10 to both sides of the equation to isolate the term with \(x\):
\[ -6x - 10 + 10 = 20 + 10 \]
This simplifies to:
\[ -6x = 30 \]
-
Next, divide both sides by -6 to solve for \(x\):
\[ x = \frac{30}{-6} \]
This simplifies to:
\[ x = -5 \]
So, the solution is \(x = -5\).
