d.

To solve the equation , let’s break it down step by step. Start by distributing the 3 on the left side:

Next, you want to get all the terms on one side and the constants on the other. Subtract from both sides:

Oops! Looks like we hit a snag! This tells us that the equation has no solutions, as does not equal . This signifies that the original equation is inconsistent.

Now onto that fun part: equations can sometimes play hard to get! It’s like a puzzle - sometimes you build your way up, only to find out there’s a piece missing. So, always check your work! If you ever end up with contradictions like this, it’s a sign to investigate further or reassess your approach. Happy solving!
