Question

1. 16 = 4(x + 9)

Explanation:

Step1: Divide both sides by 4

To isolate the term with \( x \), we divide both sides of the equation \( 16 = 4(x + 9) \) by 4. This gives us \( \frac{16}{4}=\frac{4(x + 9)}{4} \), which simplifies to \( 4=x + 9 \).

Step2: Subtract 9 from both sides

Now, to solve for \( x \), we subtract 9 from both sides of the equation \( 4=x + 9 \). This gives us \( 4-9=x+9 - 9 \), which simplifies to \( x=-5 \).

Answer:

\( x = -5 \)
