Question
$$7x+3 = 7x+3$$
Answer
The equation has an infinite number of solutions.
Explanation
$$ \begin{aligned} 7x+3 &= 7x+3&& \text{move the $ \color{blue}{ 7x } $ to the left side and $ \color{blue}{ 3 }$ to the right} \\[1 em]7x-7x &= 3-3&& \text{simplify left and right hand side} \\[1 em]7x-7x &= 0&& \\[1 em]0 &= 0&& \\[1 em] \end{aligned} $$
Since the statement $ \color{blue}{ 0 = 0 } $ is TRUE for any value of $ x $, we conclude that the equation has infinitely many solutions.
