Two Step Equations Review

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 used in the equation.

Front

What is the first step to solve the equation 9c + 1 = 10?

Back

Subtract 1 from both sides of the equation to get 9c = 9.

Front

What is the second step to solve the equation 9c = 9?

Back

Divide both sides by 9 to find c = 1.

Front

How do you solve the equation 1 + 2r = 35?

Back

First, subtract 1 from both sides to get 2r = 34, then divide by 2 to find r = 17.

Front

What is the solution to the equation 5w - 7 = 23?

Back

Add 7 to both sides to get 5w = 30, then divide by 5 to find w = 6.

Front

How do you solve for m in the equation m/5 + 9 = 11?

Back

Subtract 9 from both sides to get m/5 = 2, then multiply both sides by 5 to find m = 10.

Front

What is the first step to solve the equation y/3 - 7 = 1?

Back

Add 7 to both sides to get y/3 = 8.

Front

What is the final step to solve for y in the equation y/3 = 8?

Back

Multiply both sides by 3 to find y = 24.

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.
