Given the following equation:


3x+15=3\mleft(x+5\mright)​

You must solve for "x" as following:

1. Apply the Distributive property:


\begin{gathered} 3x+15=(3)(x)+(3)(5)​ \\ 3x+15=3x+15 \end{gathered}

2. Observe the equation. You can notice that left side is equal to right side. If you try to solve for "x", you get:


\begin{gathered} 3x-3x=15-15 \\ 0=0 \end{gathered}
