One Step Equations Addition and Subtraction

Front

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step by performing the same operation on both sides to isolate the variable.

Front

How do you solve the equation x - 11 = 8?

Back

Add 11 to both sides: x = 8 + 11, so x = 19.

Front

What is the first step to solve the equation 48 = x - 37?

Back

Add 37 to both sides: 48 + 37 = x, so x = 85.

Front

How do you isolate the variable in the equation s - 17 = 87?

Back

Add 17 to both sides: s = 87 + 17, so s = 104.

Front

What is the solution to the equation n + 6 = 61?

Back

Subtract 6 from both sides: n = 61 - 6, so n = 55.

Front

What operation do you perform to solve the equation 71 = s + 38?

Back

Subtract 38 from both sides: s = 71 - 38, so s = 33.

Front

What is the solution to the equation x - 11 = 8?

Back

Add 11 to both sides: x = 8 + 11, so x = 19.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means to manipulate the equation so that the variable is on one side by itself.

Front

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to undo the operations applied to the variable, helping to isolate it.

Front

If you have the equation x + 5 = 12, how do you solve for x?

Back

Subtract 5 from both sides: x = 12 - 5, so x = 7.
