To solve the equation
\[
-(10x + 10) = 7 + 3(-10x - 8),
\]
we'll first simplify both sides step by step.
### Step 1: Simplify the left side
The left side is:
\[
-(10x + 10) = -10x - 10.
\]
### Step 2: Simplify the right side
Now, simplify the right side. Start with:
\[
7 + 3(-10x - 8).
\]
Distribute the 3:
\[
3(-10x) + 3(-8) = -30x - 24.
\]
Now, add this to 7:
\[
7 - 30x - 24 = -30x - 17.
\]
### Step 3: Set both simplified sides equal
Now we have the equation:
\[
-10x - 10 = -30x - 17.
\]
### Step 4: Solve for \( x \)
Next, let's get all the \( x \) terms on one side and the constants on the other. Start by adding \( 30x \) to both sides:
\[
-10x + 30x - 10 = -17,
\]
which simplifies to:
\[
20x - 10 = -17.
\]
Now, add 10 to both sides:
\[
20x = -17 + 10,
\]
\[
20x = -7.
\]
Finally, divide both sides by 20 to isolate \( x \):
\[
x = \frac{-7}{20}.
\]
Thus, the solution is:
\[
\boxed{-\frac{7}{20}}.
\]
\[
-(10x + 10) = 7 + 3(-10x - 8),
\]
we'll first simplify both sides step by step.
