Flashcard one and two step/literal equations

Front

What is a literal equation?

Back

A literal equation is an equation that contains two or more variables, and it is solved for one variable in terms of the others.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, you perform inverse operations to both sides of the equation until the variable is alone on one side.

Front

What does it mean to solve an inequality?

Back

Solving an inequality means finding the range of values that satisfy the inequality condition.

Front

What is the difference between an equation and an inequality?

Back

An equation states that two expressions are equal, while an inequality shows that one expression is greater than, less than, or not equal to another.

Front

How do you check if a value satisfies an inequality?

Back

To check if a value satisfies an inequality, substitute the value into the inequality and see if the resulting statement is true.

Front

What is the solution to the inequality x + 5 > 7?

Back

The solution is x > 2.

Front

What is the solution to the equation 5 = f - 2?

Back

The solution is f = 7.

Front

What does the symbol '≤' represent in inequalities?

Back

The symbol '≤' means 'less than or equal to'.

Front

What is the first step in solving the inequality x + 9 > 21?

Back

The first step is to subtract 9 from both sides of the inequality.

Front

What is the solution to the inequality z ≤ 9?

Back

The solution indicates that z can take any value less than or equal to 9.
