One Step Equations

Front

What is an equation?

Back

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

Front

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

Back

Isolating a variable means rearranging the equation so that the variable is on one side and all other terms are on the other side.

Front

Solve the equation: x - 5 = 15

Back

x = 20

Front

Solve the equation: x - 4 = 6

Back

x = 10

Front

What is the first step to solve the equation r + 20 = 27?

Back

Subtract 20 from both sides of the equation.

Front

Solve for r: r + 20 = 27

Back

r = 7

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 the solution to the equation 15 - x = 5?

Back

x = 10

Front

What does it mean to check the solution of an equation?

Back

Checking the solution means substituting the found value back into the original equation to verify that both sides are equal.

Front

What is the goal when solving an equation?

Back

The goal is to find the value of the variable that makes the equation true.
