What do you remember from G7?

Which set of steps below correctly explains how to solve the given equation?

14x = 28

• Multiply both sides by 14

  14*14x = 28 * 14

  x = 392

• Subtract 14 from both sides

  14x - 14 = 28 - 14

  x = 14

• Divide both sides by 14

  14x ÷ 14 = 28 ÷14

  x = 2

• Add 14 to both sides

  14x + 14 = 28 + 14

  x = 42

Which set of steps below correctly explains how to solve the given equation?

72x = 34

• Multiply both sides by 72

  72 * 72x = 34 * 72

  x = 2448

• Subtract 72 from both sides

  72x - 72 = 34 - 72

  x = -38

• Divide both sides by 14

  72x ÷ 72 = 34 ÷72

  x = 34/72 = 17/36

• Add 14 to both sides

  72x + 72 = 34 + 72

  x = 106
