Given the following equation:


2x-7=-3x+18

You can solve it as follows:

1. Apply the Addition Property of Equality by adding this term to both sides of the equation:


3x

Then:


\begin{gathered} 2x-7+(3x)=-3x+18+(3x) \\ 5x-7=18 \end{gathered}

2. Apply the same property. Add 7 to both sides of the equation:


\begin{gathered} 5x-7+(7)=18+(7) \\ 5x=25 \end{gathered}

3. Finally, you can apply the Division Property of Equality by dividing both sides of the equation by 5:


\begin{gathered} (5x)/(5)=(25)/(5) \\ \\ x=5 \end{gathered}

Therefore, the answer is:


x=5
