Solving One- and Two-Step Equations

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single operation, such as addition, subtraction, multiplication, or division.

Front

What is a two-step equation?

Back

A two-step equation is an equation that requires two operations to solve for the variable.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, you perform inverse operations to get the variable alone on one side of the equation.

Front

What is the first step to solve the equation 5 + w = 17?

Back

Subtract 5 from both sides to isolate w.

Front

What is the solution to the equation 9 = r/8?

Back

Multiply both sides by 8 to find r = 72.

Front

What does it mean to perform inverse operations?

Back

Inverse operations are operations that reverse the effect of each other, such as addition and subtraction or multiplication and division.

Front

What is the first step to solve the equation -14 = r - 11?

Back

Add 11 to both sides to isolate r.

Front

How do you solve the equation 4z = 36?

Back

Divide both sides by 4 to find z = 9.

Front

What is the purpose of checking your solution in an equation?

Back

Checking your solution ensures that the value you found satisfies the original equation.

Front

What is the importance of maintaining balance in an equation?

Back

Maintaining balance means that whatever operation you perform on one side of the equation must also be performed on the other side to keep the equation true.
