Question

Solve the following equation using the addition property of equality 7p+9=15+6p

Answer 1

Given the equation:

`7p+9=15+6p`

to solve for p, we have to move the terms with the variable p to one side, and the constants to the opposite side. When we do this, we are going to change the sign of the terms that we move:

`\begin{gathered} 7p+9=15+6p \\ \Rightarrow7p-6p=15-9=6 \\ \Rightarrow p=6 \end{gathered}`

therefore, p=6
