To solve the equation:

\[
-10 + 10q - 10 = 10 + 4q
\]

### Step 1: Combine like terms on each side.

On the left-hand side:
\[
-10 - 10 + 10q = -20 + 10q
\]

So, the equation becomes:
\[
-20 + 10q = 10 + 4q
\]

### Step 2: Move all terms with the variable \( q \) to one side and constants to the other side.

Subtract \( 4q \) from both sides:
\[
-20 + 10q - 4q = 10
\]
\[
-20 + 6q = 10
\]

### Step 3: Move the constant term on the left to the right.

Add 20 to both sides:
\[
6q = 30
\]

### Step 4: Solve for \( q \).

Divide both sides by 6:
\[
q = 5
\]

### Final Answer:
\[
q = 5
\]
