Question

solve the equation $7(x + 4) = -21$,
x = \boxed{}

Explanation:

Step1: Divide both sides by 7

To isolate the term with \( x \), we divide both sides of the equation \( 7(x + 4) = -21 \) by 7. This gives us \( \frac{7(x + 4)}{7} = \frac{-21}{7} \), which simplifies to \( x + 4 = -3 \).

Step2: Subtract 4 from both sides

To solve for \( x \), we subtract 4 from both sides of the equation \( x + 4 = -3 \). This gives us \( x + 4 - 4 = -3 - 4 \), which simplifies to \( x = -7 \).

Answer:

\( x = -7 \)
