To solve for \( x \) in the equation \( 4x = 3(x + 5) - 15 \):
-
Start by distributing the \( 3 \) on the right side: \[ 4x = 3x + 15 - 15 \] This simplifies to: \[ 4x = 3x \]
-
Next, subtract \( 3x \) from both sides: \[ 4x - 3x = 0 \] This simplifies to: \[ x = 0 \]
Now, let's see if this situation indicates one, none, or infinite solutions.
Since we found one solution, \( x = 0 \), there is indeed one solution to this equation.
The appropriate response is: The equation has one solution: x = 0.
