Solving 2-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

What is the first step to solve the equation -5t + 9 = 24?

Back

Subtract 9 from both sides to isolate the term with the variable.

Front

What is the second step to solve the equation -5t = 15?

Back

Divide both sides by -5 to solve for t.

Front

Solve the equation: 12 - 6y = 24

Back

y = -2

Front

What does it mean to isolate a variable in an equation?

Back

To isolate a variable means to get the variable alone on one side of the equation.

Front

What is the solution to the equation 7 - 3y = 22?

Back

y = -5

Front

How do you check if your solution to an equation is correct?

Back

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

Front

Solve the equation: 2x - 3 = 1

Back

x = 2

Front

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

Back

Inverse operations are used to undo the operations applied to the variable, helping to isolate it.

Front

What is the first step to solve the equation -5t + 9 = 24?

Back

Subtract 9 from both sides to get -5t = 15.
