Place two tikzpictures next to eachother LaTeX - pdf

Question

I have two tikzpitctures in LaTeX that I was hoping to place side-by-side. Does anybody know a solid way of accomplishing this? If not, is there another approach to creating side-by-side Venn Diagrams?
Code:
% %%%%%%%%%%%%%%%%%%%
\section*{Question 1}
% %%%%%%%%%%%%%%%%%%%
{\bfseries Determine the relationship between $P = (A-B)-C$ and $Q = (A-C)-(B-C)$}
{\bfseries Answer: $P = Q$}
% %%%%%%%%%%%%%%%%%%%
\subsection*{Justification 1: Venn Diagram}
% %%%%%%%%%%%%%%%%%%%
\def\firstcircle{ (0.0, 0.0) circle (1.5)}
\def\secondcircle{(2.0, 0.0) circle (1.5)}
\def\thirdcircle{ (1.0,-1.5) circle (1.5)}
\def\rectangle{ (-1.5,-3.0) rectangle (3.5,1.0) }
\colorlet{circle edge}{black}
\colorlet{circle area}{blue!30}
\tikzset{filled/.style={fill=circle area, draw=circle edge, thick},
outline/.style={draw=circle edge, thick}}
\begin{tikzpicture}
\begin{scope}
\fill[filled] \firstcircle;
\fill[white] \secondcircle;
\fill[white] \thirdcircle;
\end{scope}
\draw[outline] \firstcircle node[left] {$A$};
\draw[outline] \secondcircle node[right] {$B$};
\draw[outline] \thirdcircle node[below] {$C$};
\node[anchor=south] at (current bounding box.north)
{$P = (A - B) - C$};
\end{tikzpicture}
\begin{tikzpicture}
\begin{scope}
\fill[filled] \firstcircle;
\fill[white] \secondcircle;
\fill[white] \thirdcircle;
\end{scope}
\draw[outline] \firstcircle node[left] {$A$};
\draw[outline] \secondcircle node[right] {$B$};
\draw[outline] \thirdcircle node[below] {$C$};
\node[anchor=south] at (current bounding box.north)
{$Q = (A - C) - (B - C)$};
\end{tikzpicture}
\pagebreak

Answer 1

You force the two images to be in separate lines by leaving an empty line between the two pictures. For latex an empty line marks the start of a new paragraph.

Answer 2

You can always draw a huge
Grid, I have this exact problem... and I draw a grid,
Especially if your scheme is a progression where most things stay the same..but a few things change for each new image... like a cartoon... you will just have the alter the coordinates when you copy the new picture..
It’s very easy to space everything and tailor it to your aesthetic...
You can even use different step sizes on the grid.
Once you’ve drawn the total scheme, change the grid lines to white and it doesn’t show in the rendered pdf..
Hope that helps
