An equation with no solution occurs when the two sides of the equation cannot be equal for any value of the variable.
Let's analyze the provided options:
-
3x + 4 = 3x + 4
This simplifies to 0 = 0, which is true for any x. Thus, it has infinitely many solutions. -
4x + 3 = 3x + 3
This simplifies to x = 0, which has one solution. -
3x + 4 = 4x + 3
This simplifies to x = 1, which has one solution. -
3x + 4 = 3x + 3
This simplifies to 4 = 3, which is a false statement. Therefore, it has no solutions.
So, the equation with no solution is 3x + 4 = 3x + 3.
