To determine which of the given equations has no solution, let's analyze each option step-by-step.
A) \( 4x + 3 = 3x + 3 \)
Subtract \( 3x \) from both sides:
\( 4x - 3x + 3 = 3 \)
This simplifies to:
\( x + 3 = 3 \)
Now subtract 3 from both sides:
\( x = 0 \)
This equation has a solution (\( x = 0 \)).
B) \( 3x + 4 = 4x + 3 \)
Subtract \( 3x \) from both sides:
\( 4 = x + 3 \)
Subtract 3 from both sides:
\( 1 = x \)
This equation has a solution (\( x = 1 \)).
C) \( 3x + 4 = 3x + 4 \)
This equation is true for all values of \( x \), indicating an infinite number of solutions, not no solution.
D) \( 3x + 4 = 3x + 3 \)
Subtract \( 3x \) from both sides:
\( 4 = 3 \)
This statement is false, meaning there is no value of \( x \) that can satisfy the equation.
Thus, the correct answer is:
D) \( 3x + 4 = 3x + 3 \), which has no solution.
