One and Two Step Equations Review

Front

What is a one-step equation?

Back

A one-step equation is an 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 equation that requires two operations to isolate the variable, usually involving addition or subtraction followed by multiplication or division.

How do you solve the equation 4x + 10 = -26?

Back

To solve 4x + 10 = -26, first subtract 10 from both sides to get 4x = -36, then divide both sides by 4 to find x = -9.

Front

What is the first step to solve the equation 6b = 30?

Back

The first step is to divide both sides of the equation by 6 to isolate b, resulting in b = 5.

Front

How do you isolate x in the equation x - 8 = -5?

Back

To isolate x, add 8 to both sides of the equation, resulting in x = 3.

Front

What is the solution to the equation 19 + a = -50?

Back

To solve for a, subtract 19 from both sides, resulting in a = -69.

Front

How do you solve the equation -5z + 5 = -30?

Back

First, subtract 5 from both sides to get -5z = -35, then divide both sides by -5 to find z = 7.

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 manipulating the equation so that the variable is on one side by itself, allowing you to find its value.
