Question

complete the process of solving the equation. fill in the missing term and select the missing description. simplify any fractions. 6(r + 1) = 12 r + 1 = 2 r = add 6 to both sides subtract 6 from both sides multiply both sides by 6 divide both sides by 6 combine like terms

Explanation:

Step1: Identify the operation for \(6(r + 1)=12\) to \(r + 1 = 2\)

To get from \(6(r + 1)=12\) to \(r + 1 = 2\), we divide both sides of the equation by 6. So the missing description is "Divide both sides by 6".

Step2: Solve \(r + 1 = 2\) for \(r\)

Subtract 1 from both sides of the equation \(r + 1 = 2\).
\(r+1 - 1=2 - 1\)
\(r = 1\)

Answer:

The missing description is "Divide both sides by 6" and the value of \(r\) is \(1\). So the completed equation steps are:

• From \(6(r + 1)=12\) to \(r + 1 = 2\): Divide both sides by 6.
• From \(r + 1 = 2\) to \(r=\boxed{1}\): Subtract 1 from both sides (implied in the calculation).
