2 step equations - no negatives

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 in solving the equation x + 5 = 12?

Back

Subtract 5 from both sides of the equation.

Front

What is the solution to the equation 2x = 10?

Back

x = 5, obtained by dividing both sides by 2.

Front

What does it mean if an equation has no solution?

Back

It means that there is no value for the variable that can satisfy the equation.

Front

What is the solution to the equation x - 3 = 4?

Back

x = 7, obtained by adding 3 to both sides.

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 importance of maintaining balance in an equation?

Back

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

Front

What is the solution to the equation 3x + 6 = 24?

Back

x = 6, obtained by first subtracting 6 from both sides and then dividing by 3.

Front

What is the role of inverse operations in solving equations?

Back

Inverse operations are used to undo the operations applied to the variable, allowing for isolation.
