Why must I do the same operation on both sides of the equation?

• In order to keep both sides of the equations unbalanced because both are equal.

• In order to keep both sides of the equation balanced because both sides are equal.

• To find what the variable equals

• To find the inverse

How do we know when an equation is true?

• When the left side of the equation is greater than the right side of the equation

• When the right side of the equation is greater than the left side of the equation.

• When both sides of the equation equals zero

• When the value of the left side of the equation equals the value on the right side of the equation.

When solving for the value of a variable, why must the variable be isolated or alone?

• In order to find the coefficient

• In order to find its value

• In order to find the equation

• In order to find the inverse
