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 the inverse operations in the reverse order of how they are applied.

Front

What is the first step to solve the equation 2t - 7 = 3?

Back

Add 7 to both sides of the equation to isolate the term with the variable.

Front

What is the solution to the equation 2t - 7 = 3?

Back

The solution is t = 5.

Front

How do you solve the equation 13 = 5m - 2?

Back

First, add 2 to both sides to get 15 = 5m, then divide by 5 to find m = 3.

Front

What is the solution to the equation \( \frac{x}{4} + 8 = 10 \)?

Back

Subtract 8 from both sides to get \( \frac{x}{4} = 2 \), then multiply by 4 to find x = 8.

Front

What is the first step to solve the equation 5x - 1 = 19?

Back

Add 1 to both sides of the equation to isolate the term with the variable.

Front

What is the solution to the equation 5x - 1 = 19?

Back

The solution is x = 4.

Front

How do you solve the equation x/4 + 2 = 42?

Back

Subtract 2 from both sides to get x/4 = 40, then multiply by 4 to find x = 160.

Front

What is the importance of checking your solution in a two-step equation?

Back

Checking your solution ensures that the value satisfies the original equation, confirming its correctness.
