Question

what is the value of 1 group of x + 4? show this on the hanger diagram.
18
18 = 2(x + 4)

Explanation:

Step1: Solve the equation for \(x + 4\)

Given the equation \(18 = 2(x + 4)\), we can divide both sides by 2 to isolate the term \((x + 4)\).
\[
\frac{18}{2}=\frac{2(x + 4)}{2}
\]

Step2: Simplify both sides

Simplifying the left side gives \(9\), and the right side simplifies to \((x + 4)\) since the 2 in the numerator and denominator cancels out.
\[
9=x + 4
\]
But we just needed the value of one group of \(x + 4\), and from the first step, when we divided 18 by 2, we found that \(x + 4 = 9\).

Answer:

The value of 1 group of \(x + 4\) is \(\boldsymbol{9}\).
