Questions & Step-by-Step Solutions

Solve the inequality 3x - 5 < 7.
  • Step 1: Start with the inequality 3x - 5 < 7.
  • Step 2: Add 5 to both sides of the inequality to get rid of the -5. This gives you 3x < 7 + 5.
  • Step 3: Simplify the right side. 7 + 5 equals 12, so now you have 3x < 12.
  • Step 4: Now, divide both sides of the inequality by 3 to solve for x. This gives you x < 12 / 3.
  • Step 5: Simplify the right side. 12 divided by 3 equals 4, so you have x < 4.
