Multi-Step with Special Solutions

Front

What does it mean when an equation has 'no solution'?

Back

An equation has 'no solution' when there are no values for the variable that can satisfy the equation, often resulting in a contradiction.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means rearranging the equation so that the variable is on one side and all other terms are on the opposite side.

Front

What is the significance of the distributive property in solving equations?

Back

The distributive property allows you to multiply a single term by each term inside a parenthesis, which is essential for simplifying expressions in equations.

What is the solution to the equation 2(x + 5) = 2x + 5?

Back

The solution is 'no solution' because both sides simplify to the same expression, leading to a contradiction.

Front

How can you check your solution to an equation?

Back

You can check your solution by substituting the value back into the original equation to see if both sides are equal.
