What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac, meaning you can distribute a factor across a sum.

What does it mean to combine like terms?

Back

Combining like terms involves adding or subtracting terms that have the same variable raised to the same power.

How do you isolate a variable in an equation?

Back

To isolate a variable, you perform inverse operations to get the variable alone on one side of the equation.

What does it mean to move a variable to the other side of the equation?

Back

Moving a variable to the other side involves using inverse operations to shift the variable from one side of the equation to the other.

Front

What is the role of constants in multistep equations?

Back

Constants are fixed values that can be moved across the equation using inverse operations, often to isolate the variable.
