Simplify each expression. See Example 8. -12y + 4y + 3y + 2y

검증된 단계별 안내

Identify the like terms in the expression: all terms contain the variable \(y\), so they can be combined.

Write the expression grouping the coefficients of \(y\): \(-12y + 4y + 3y + 2y\).

Add the coefficients together: calculate \(-12 + 4 + 3 + 2\).

Combine the sum of the coefficients with the variable \(y\) to form the simplified expression.

Write the final simplified expression as the product of the combined coefficient and \(y\).

Combining Like Terms

Combining like terms involves adding or subtracting terms that have the same variable raised to the same power. In this expression, all terms contain the variable y, so their coefficients can be summed to simplify the expression.

Coefficients in Algebraic Expressions

A coefficient is the numerical factor in a term of an algebraic expression. Understanding how to add and subtract coefficients correctly is essential for simplifying expressions involving variables.

Simplification of Algebraic Expressions

Simplification means rewriting an expression in its simplest form by performing all possible operations. This process makes expressions easier to work with and understand, often by reducing the number of terms.
