Solving 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 inverse operations in the reverse order of operations.

Front

What is the first step to solve the equation 0 = 8z + 8?

Back

Subtract 8 from both sides to get -8 = 8z.

Front

What is the solution to the equation 3n + 4 = 7?

Back

The solution is n = 1.

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

What does it mean to 'balance' an equation?

Back

Balancing an equation means keeping both sides equal by performing the same operation on both sides.

Front

What is the solution to the equation 9 = 2s + 1?

Back

The solution is s = 4.

Front

What is the second step to solve the equation -5 = 3m - 14?

Back

Add 14 to both sides to get 9 = 3m.

Front

What is the solution to the equation 4c - 6 = 2?

Back

The solution is c = 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, allowing us to isolate it.
