Question
$$3(2x+2)-3x = 6+3x$$
Answer
The equation has an infinite number of solutions.
Explanation
$$ \begin{aligned} 3(2x+2)-3x &= 6+3x&& \text{simplify left and right hand side} \\[1 em]6x+6-3x &= 3x+6&& \\[1 em]3x+6 &= 3x+6&& \text{move the $ \color{blue}{ 3x } $ to the left side and $ \color{blue}{ 6 }$ to the right} \\[1 em]3x-3x &= 6-6&& \text{simplify left and right hand side} \\[1 em]3x-3x &= 0&& \\[1 em]0 &= 0&& \\[1 em] \end{aligned} $$
Since the statement $ \color{blue}{ 0 = 0 } $ is TRUE for any value of $ x $, we conclude that the equation has infinitely many solutions.
