question 8
solve for x.
9 + 6x = -21
x =

Explanation:

Step1: Subtract 9 from both sides

To isolate the term with \( x \), we subtract 9 from both sides of the equation \( 9 + 6x = -21 \). This gives us \( 9 + 6x - 9 = -21 - 9 \), which simplifies to \( 6x = -30 \).

Step2: Divide by 6

Now, to solve for \( x \), we divide both sides of the equation \( 6x = -30 \) by 6. So, \( \frac{6x}{6} = \frac{-30}{6} \), which simplifies to \( x = -5 \).

Answer:

\( x = -5 \)
