Explanation:

To solve this, we analyze each step:

Step 2:
  • Explanation: We apply the distributive property to expand \(-\frac{2}{3}(x + 12)\). The distributive property states \(a(b + c)=ab + ac\), so \(-\frac{2}{3}(x + 12)=-\frac{2}{3}x-\frac{2}{3}(12)=-\frac{2}{3}x - 8\).
  • Reason: distributive property
Step 3:
  • Explanation: Combine the like terms \(-\frac{2}{3}x\) and \(\frac{1}{3}x\). \(-\frac{2}{3}x+\frac{1}{3}x=-\frac{1}{3}x\), so we simplify the equation.
  • Reason: combine like terms
Step 4:
  • Explanation: Add 8 to both sides of the equation (addition property of equality: if \(a = b\), then \(a + c = b + c\)). Adding 8 to both sides of \(-6=-\frac{1}{3}x - 8\) gives \(-6 + 8=-\frac{1}{3}x-8 + 8\), so \(2=-\frac{1}{3}x\).
  • Reason: addition property of equality
Step 5:
  • Explanation: Multiply both sides by \(-3\) (multiplication property of equality: if \(a = b\), then \(ac = bc\)). Multiplying \(2=-\frac{1}{3}x\) by \(-3\) gives \(2(-3)=-\frac{1}{3}x(-3)\), so \(-6 = x\).
  • Reason: multiplication property of equality
Step 6:
  • Explanation: Use the symmetric property, which states if \(a = b\), then \(b = a\). Since \(-6 = x\), we can rewrite it as \(x = -6\).
  • Reason: symmetric property
