To solve the equation \( 4x = 3(x + 5) - 15 \), let's begin by simplifying the right side:
-
Distribute \( 3 \) in \( 3(x + 5) \): \[ 3(x + 5) = 3x + 15 \] So the equation becomes: \[ 4x = 3x + 15 - 15 \] Simplifying further gives: \[ 4x = 3x \]
-
Next, we'll subtract \( 3x \) from both sides: \[ 4x - 3x = 0 \] This simplifies to: \[ x = 0 \]
Since the equation resolved to \( x = 0 \), this tells us that the equation has one solution.
Thus, the correct response is: The equation has one solution: x = 0.
