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 used in the equation.

Front

What is the first step to solve the equation 7k - 14 = 42?

Back

Add 14 to both sides of the equation to eliminate the constant term.

Front

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

Back

The solution is s = 4.

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 -5 = 3m - 14?

Back
