One and Two Step Equations

Front

What is a one-step equation?

Back

An equation that can be solved in one step, typically by performing a single operation (addition, subtraction, multiplication, or division) to isolate the variable.

Front

What is a two-step equation?

Back

An equation that requires two steps to solve, usually involving two operations to isolate the variable.

Front

Back

Multiply both sides by 4, then add 7 to both sides.

Front

How do you isolate a variable in an equation?

Back

By performing inverse operations to both sides of the equation until the variable is alone on one side.

Front

Back

n=6.

Front

What does it mean to 'add 11 to both sides' of an equation?

Back

It means to perform the same operation (adding 11) on both sides of the equation to maintain equality.

Front

Back

u = 3.

Front

Back

Add 11 to both sides.

Front

Back

w = 12.

Front

What is the purpose of using inverse operations in solving equations?

Back

To reverse the effect of operations applied to the variable, allowing us to isolate it.
