One and Two-Step Equations

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step, typically by performing the inverse operation to isolate the variable.

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two steps to solve, usually involving two inverse operations to isolate the variable.

How do you solve the equation 7x = 21?

Back

To solve 7x = 21, divide both sides by 7 to isolate x, resulting in x = 3.

Front

What is the inverse operation of addition?

Back

The inverse operation of addition is subtraction.

Front

What is the inverse operation of multiplication?

Back

The inverse operation of multiplication is division.

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 solution to the equation x + 5 = 12?

Back

To solve x + 5 = 12, subtract 5 from both sides, resulting in x = 7.

Front

What is the solution to the equation 2x - 4 = 10?

Back

To solve 2x - 4 = 10, first add 4 to both sides to get 2x = 14, then divide by 2 to find x = 7.

Front

What is a variable in an equation?

Back

A variable is a symbol, often represented by a letter, that stands for an unknown value in an equation.

Front

What is the purpose of solving equations?

Back

The purpose of solving equations is to find the value of the variable that makes the equation true.
