Solving One Step Equations using Addition or Subtraction

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step, typically involving addition or subtraction to isolate the variable.

Front

How do you solve the equation w + 14 = 10?

Back

Subtract 14 from both sides: w = 10 - 14, so w = -4.

Front

What is the solution to the equation x - 10 = 12?

Back

Add 10 to both sides: x = 12 + 10, so x = 22.

Front

How do you solve the equation y + 6 = 20?

Back

Subtract 6 from both sides: y = 20 - 6, so y = 14.

Front

What is the solution to the equation a + 4 = 14?

Back

Subtract 4 from both sides: a = 14 - 4, so a = 10.

Front

How do you solve the equation 25 + k = 13?

Back

Subtract 25 from both sides: k = 13 - 25, so k = -12.

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, making it easier to solve.

Front

What is the inverse operation of addition?

Back

The inverse operation of addition is subtraction.

Front

What is the inverse operation of subtraction?

Back

The inverse operation of subtraction is addition.

Front

If you have the equation x + 5 = 15, how do you find x?

Back

Subtract 5 from both sides: x = 15 - 5, so x = 10.
