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. It typically involves isolating the variable on one side of the equation.

Front

How do you isolate a variable in a two-step equation?

Back

To isolate a variable in a two-step equation, you perform the inverse operations in the reverse order of how they are applied. First, eliminate the constant term, then divide or multiply to solve for the variable.

Front

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

Back

The first step is to subtract 1 from both sides of the equation to eliminate the constant term.

Front

What is the solution to the equation -4 = 2t - 2?

Back

The solution is t = -1.

Front

What operation would you perform first to solve the equation 8 = 4v + 12?

Back

You would first subtract 12 from both sides of the equation.

Front

What is the solution to the equation -5 = 3m - 14?

Back

The solution is m = 3.

Front

How do you check if your solution to a two-step equation is correct?

Back

To check if your solution is correct, substitute the value of the variable back into the original equation and verify if both sides are equal.

Front

What is the inverse operation of addition?

Back

The inverse operation of addition is subtraction.

Front

What is the inverse operation of multiplication?

Back

The inverse operation of multiplication is division.

Front

In the equation 0 = 8z + 8, what is the first step to solve for z?

Back

The first step is to subtract 8 from both sides of the equation.
