The equation that is equivalent to x + 8 = 21 is (x + 8) × 4 = 21 × 4

Given the equation

  • x + 8 = 21

To get a similar expression we will either subtract, multiply, divide or add the same constant to both sides of the equation

Multiplying both sides by 4 will give:

  • x + 8 = 21
  • (x + 8) * 4= 21 * 4

Hnce the equation that is equivalent to x + 8 = 21 is (x + 8) × 4 = 21 × 4
