Question

2(-3x + 7) + (-6x + 9) =

Explanation:

Step1: Remove parentheses

We have the expression \(2(-3x + 7)+(-6x + 9)\). First, distribute the 2 in the first parentheses: \(2\times(-3x)+2\times7+(-6x + 9)\), which simplifies to \(-6x + 14 - 6x + 9\).

Step2: Combine like terms

Now, combine the \(x\)-terms and the constant terms. For the \(x\)-terms: \(-6x-6x=-12x\). For the constant terms: \(14 + 9 = 23\). So the simplified expression is \(-12x+23\).

Answer:

\(-12x + 23\)
