Modeling Equations

Front

What is the equation modeled by the expression: x + 6 = 13?

Back

To find x, subtract 6 from both sides: x = 13 - 6, so x = 7.

Front

What is the equation modeled by the expression: 3x = 6?

Back

To find x, divide both sides by 3: x = 6 / 3, so x = 2.

Front

What does the equation 2x + 4 = 10 represent?

Back

This equation shows that when you double a number (x) and add 4, the result is 10.

Front

How do you solve the equation 7x + 3 = 23?

Back

Subtract 3 from both sides: 7x = 20, then divide by 7: x = 20 / 7.

Front

What is the solution to the equation 4x + 3 = 9?

Back

Subtract 3 from both sides: 4x = 6, then divide by 4: x = 6 / 4, which simplifies to x = 1.5.

Front

What does the equation 3 = 6x represent?

Back

This equation shows that 6 times a number (x) equals 3.

Front

What is the first step to solve the equation x - 6 = 13?

Back

Add 6 to both sides: x = 13 + 6, so x = 19.

Front

What is the meaning of the term 'algebra tiles'?

Back

Algebra tiles are physical or virtual manipulatives used to represent variables and constants in algebraic expressions.

Front

What does the equation 3x - 8 = 3 mean?

Back

This equation indicates that if you subtract 8 from three times a number (x), the result is 3.

Front

How do you represent the equation 3x = 24 using algebra tiles?

Back

You would use 3 groups of x tiles and 24 unit tiles to show the equation.
