2 Step Equation Models

Front

What is a two-step equation?

Back

A two-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

What does the variable 'm' represent in the equation 3m + 2 = 14?

Back

The variable 'm' represents an unknown value that we need to solve for.

Front

How do you isolate the variable in a two-step equation?

Back

To isolate the variable, perform the inverse operations in reverse order: first undo the addition or subtraction, then undo the multiplication or division.

Front

What is the first step to solve the equation 3m + 2 = 14?

Back

The first step is to subtract 2 from both sides of the equation.

Front

What is the solution to the equation 3m + 2 = 14?

Back

The solution is m = 4.

Front

What do algebra tiles represent in equations?

Back

Algebra tiles represent variables and constants; for example, squares can represent '1' and rectangles can represent 'x'.

Front

In the equation 2x - 9 = 5, what does '2x' represent?

Back

'2x' represents two times the value of the variable x.

Front

How do you check if your solution to a two-step equation is correct?

Back

Substitute the solution back into the original equation to see if both sides are equal.

Front

What is the value of x in the equation 2x - 9 = 5?

Back

The value of x is 7.

Front

What does it mean to model an equation with shapes?

Back

Modeling an equation with shapes helps visualize the relationship between variables and constants, making it easier to understand and solve.
