Expression or Equation

Front

What is an equation?

Back

An equation is a mathematical statement that shows the equality of two expressions, often containing variables. For example, 16 ÷ f = 4 is an equation.

What is an expression?

Back

An expression is a combination of numbers, variables, and operators (like +, -, ×, ÷) that represents a value but does not include an equality sign. For example, 14x + 6 is an expression.

Identify the type: 15 = d – 36

Back

This is an equation.

Front

Identify the type: 14x + 6

Back

This is an expression.

Front

What does the variable 'f' represent in the equation 16 ÷ f = 4?

Back

In this equation, 'f' represents a number that, when 16 is divided by it, equals 4.

Front

What is the solution to the equation b + 3 = 19?

Back

To solve for b, subtract 3 from both sides: b = 19 - 3, so b = 16.

Front

What is the solution to the equation 16 ÷ f = 4?

Back

To solve for f, multiply both sides by f and then divide by 4: f = 16 ÷ 4, so f = 4.

Front

What is the solution to the equation 15 = d – 36?

Back

To solve for d, add 36 to both sides: d = 15 + 36, so d = 51.

Identify the type: 7y

Back

This is an expression.

Front

What is the difference between an expression and an equation?

Back

An expression does not have an equality sign and represents a value, while an equation states that two expressions are equal.
