Solving One Step Equations using Addition or Subtraction

Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions, typically containing variables.

Front

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

Back

Isolating a variable means manipulating the equation to get the variable alone on one side of the equation.

Front

In the equation x + 7 = 12, how do you isolate x?

Back

Subtract 7 from both sides to get x = 5.

Front

What is the first step to solve the equation w + 14 = 10?

Back

Subtract 14 from both sides to isolate w.

Front

What is the solution to the equation 20.5 = x + 4?

Back

x = 16.5.

Front

How do you represent 'Janna is 3 years older than Zak' in an equation?

Back

z + 3 = 12, where z is Zak's age.

Front

What is the solution to the equation m - 5 = -10?

Back

m = -5 + 5, so m = -5.

Front

What operation do you perform to both sides of the equation to maintain equality?

Back

You can add, subtract, multiply, or divide both sides by the same number.

Front

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

Back

Inverse operations help to undo the operations applied to the variable, allowing you to isolate it.

Front

If you have the equation x + 3 = 10, what is x?

Back

x = 10 - 3, so x = 7.
