Hi there! The answer is 0 solutions.
[tex]3(x + 4) = 3x + 4[/tex]
First we need to work out the parenthesis (for instance possible by using rainbow technique).
[tex]3x + 12 = 3x + 4[/tex]
Now subtract 12.
[tex]3x = 3x - 8[/tex]
Now we can see that the right side of the equation is always 8 smaller than the left side of the equation. Because the right is always smaller, this equation cannot be solved. Therefore there are no solutions to this equation. The answer is 0 solutions.
