Two-Step Equations

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

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

Back

To isolate a variable, perform the inverse operations in the reverse order of how they are applied.

Front

What is the first step to solve the equation -15 = -4t + 5?

Back

The first step is to subtract 5 from both sides of the equation.

Front

What is the solution to the equation 4w - 9 = -9?

Back

The solution is w = 0.

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 solution to the equation 2r + 10 = -2?

Back

The solution is r = -6.

Front

What operation would you perform first to solve the equation 6 + (x/2) = 4?

Back

You would first subtract 6 from both sides of the equation.

Front

What is the solution to the equation (z/2) + 5 = 3?

Back

The solution is z = -4.

Front

What does it mean to perform the inverse operation?

Back

Performing the inverse operation means applying the opposite mathematical operation to eliminate a term.

Front

What is the importance of maintaining balance in an equation?

Back

Maintaining balance ensures that both sides of the equation remain equal after performing operations.
