Simplifying, Adding and Subtracting Expressions

Front

Simplify the expression: 3x + 2y - 5x + 4y

Back

-2x + 6y

Front

Identify the constant in the expression: 4a - 7b + 9

Back

9

Front

Add the expressions: (6a - 2b) + (3a + 4b)

Back

9a + 2b

Front

Apply the distributive property: 5(3a - 2b)

Back

15a - 10b

Front

Simplify the expression: 7a - 3b + 2a + 5b

Back

9a + 2b

Front

What is a variable in an expression?

Back

A symbol (like x or y) that represents a number.

Front

What is a coefficient?

Back

A number that multiplies a variable (e.g., in 4x, 4 is the coefficient).

Front

What does it mean to combine like terms?

Back

To add or subtract terms that have the same variable raised to the same power.

Front

What is the distributive property?

Back

a(b + c) = ab + ac; it allows you to multiply a term by a sum.

Front

What is a constant in an expression?

Back

A fixed value that does not change (e.g., in 4a + 5, 5 is a constant).
