Tell me what went wrong when solving this inequality.

Answer explanation

The multiplier (4x) is not negative, so they did not have to reverse the inequality signs.

• Divide all three sides by 3x

• Add 19 to all three sides

• Add 5 to all three sides

• Subtract 1 from all three sides

Answer explanation

You are trying to get x by itself so the first thing you need to do is add 5 to each part of the inequality.

Answer explanation

Step 1: Subtract 6 from all three parts of the inequality
