What should be done to solve the equation? x+14=21 add 14 to both sides of the equation. subtract 14 from the left side of the equation. add 14 to the left side and subtract 14 from the right side of the equation. subtract 14 from both sides of the equation.

  Subtract 14 from both sides of the equation.

Step-by-step explanation:

The subtraction property of equality tells you the equal sign only remains valid if you subtract the same value from both sides of the equation.

Here, we want the 14 on the left side to be replaced by 0. Thus we must add its opposite. Since we must do the same thing to both sides of the equation, we must subtract 14 from both sides of the equation.

Last option:  Subtract 14 from both sides of the equation.

Step-by-step explanation:

To solve the equation you must solve for the variable "x".

To calculate the value of the variable "x" it is important to remember the Subtraction property of equality. This states that:

Therefore, applying this property, you should subtract 14 from both sides of the equation to find the value of the variable "x". Then:
