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 how they are applied in the equation.

Front

What is the first step to solve the equation 3n + 4 = 7?

Back

Subtract 4 from both sides of the equation to begin isolating the variable.

Front

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

Back

Front

How do you solve the equation 5d - 6 = 9?

Back

First, add 6 to both sides, then divide by 5 to isolate d.

Front

What is the solution to the equation 5d - 6 = 9?

Back

The solution is d = 3.

Front

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

Back

Subtract 1 from both sides, then divide by 2 to find s.

Front

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

Back

The solution is s = 4.

Front

How do you solve the equation -4 = 2t - 2?

Back

Add 2 to both sides, then divide by 2 to isolate t.
