Question

simplify $3 - 4y + (-7y) + 8.1$.

$3 - 4y + (-7y) + 8.1 = \square$
(simplify your answer. use integers or decimals for any numbers in the expression.)

Explanation:

Step1: Combine like terms (constants)

Add the constant terms \(3\) and \(8.1\). So, \(3 + 8.1 = 11.1\).

Step2: Combine like terms (terms with \(y\))

Add the coefficients of \(y\): \(-4y + (-7y)=-4y - 7y=-11y\).

Step3: Combine the results

Combine the results from Step 1 and Step 2. So, the simplified expression is \(11.1 - 11y\) (or \(-11y + 11.1\)).

Answer:

\(11.1 - 11y\) (or \(-11y + 11.1\))
