Question

solve the equation $5(p - 2) = 20$. how can you isolate the variable $p$? $5(p - 2) = 20$ $5p - 10 = 20$ $\\ \\ \\ \\ + 10\\ \\ \\ + 10$ \\(\longleftarrow\\) add 10 on both sides. $5p = 30$ \\(\boldsymbol{?}\\) on both sides.

Explanation:

Step1: Analyze the equation after adding 10

We have \(5p = 30\). To isolate \(p\), we need to perform an operation that will leave \(p\) alone. Since \(p\) is multiplied by 5, we use the inverse operation of multiplication, which is division.

Step2: Perform the operation

We divide both sides of the equation \(5p = 30\) by 5. So the operation is "Divide" and the number is "5".

Answer:

Divide, 5
