To solve the equation \( 4x = 3(x + 5) - 15 \), we will simplify and solve for \( x \).
-
Start by distributing the \( 3 \) on the right side: \[ 4x = 3x + 15 - 15 \] This simplifies to: \[ 4x = 3x \]
-
Next, subtract \( 3x \) from both sides of the equation: \[ 4x - 3x = 0 \] This leads to: \[ x = 0 \]
The solution \( x = 0 \) indicates that there is one solution.
Thus, the correct response is: The equation has one solution: x=0.
