Question

write an equation that represents the weights on the hanger. 2a + 1 = 9
what is the value of a?
a = \square

Explanation:

Step1: Subtract 1 from both sides

To isolate the term with \(a\), we subtract 1 from both sides of the equation \(2a + 1 = 9\). This gives us \(2a + 1 - 1 = 9 - 1\), which simplifies to \(2a = 8\).

Step2: Divide both sides by 2

To solve for \(a\), we divide both sides of the equation \(2a = 8\) by 2. So, \(\frac{2a}{2}=\frac{8}{2}\), which simplifies to \(a = 4\).

Answer:

\(a = 4\)
