Solving One Steps, Distributing, and Combining like terms-REVIEW

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and -9x are like terms because they both contain the variable x.

How do you simplify the expression -8(6x + 3)?

Back

To simplify, distribute -8: -8 * 6x = -48x and -8 * 3 = -24. So, the simplified expression is -48x - 24.

How do you simplify the expression -10x + 15 - 3x + 2?

Back

Combine like terms: -10x - 3x = -13x and 15 + 2 = 17. The simplified expression is -13x + 17.

What does it mean to distribute in algebra?

Back

Distributing means multiplying a single term by each term inside a set of parentheses. For example, in -8(6x + 3), you distribute -8 to both 6x and 3.

What are the steps to combine like terms?

Back

Identify terms with the same variable and exponent, then add or subtract their coefficients. For example, 3x + 2x = 5x.

What is the difference between like terms and unlike terms?

Back

Like terms have the same variable and exponent, while unlike terms do not. For example, 3x and 4y are unlike terms.

How do you isolate a variable in an equation?

Back

To isolate a variable, perform inverse operations to move all other terms to the opposite side of the equation.
