Question

solve for r. -4(r + 10) = 12 r = submit

Explanation:

Step1: Divide both sides by -4

To isolate the term with \( r \), we divide both sides of the equation \(-4(r + 10) = 12\) by \(-4\). This gives us \( \frac{-4(r + 10)}{-4} = \frac{12}{-4} \), which simplifies to \( r + 10 = -3 \).

Step2: Subtract 10 from both sides

To solve for \( r \), we subtract 10 from both sides of the equation \( r + 10 = -3 \). So, \( r + 10 - 10 = -3 - 10 \), which simplifies to \( r = -13 \).

Answer:

\( r = -13 \)
